L-27 - NIPER JEE 2026 | Pharmacognosy: Glycosides | 360 Series #niper #niper2026 #Glycosides

Added: 2026-05-24

[00:00:00]Hello everyone welcome see you all in GDC student today in NIPER 360 series there is an important topic of pharmacognosy whose name is glycoside and what we are going to do here is we are going to see and solve 30 important questions of that glycoside which you might have seen somewhere in the previous year NIPER examinations from where questions have been asked.

[00:00:21]Ok? Let us come to the first question which was asked in Sniper J Double 2024 and what is the question saying sir? That sweetening principle of licorice is due to licorice being a glycoside. Basically it is known as liquorice. In licorice, you must have read its synonym as mulethi. There is a sweetening principle in it, why does it happen?

[00:00:49]Due to glycerin, due to licorice, due to isoleucine or due to carbanion?

[00:00:54]So sir the biological source of liquefaction is Glycyrrhiza glabra and from the same Glycyrrhiza glabra students what can you do with glycerin here? Can connect.

[00:01:03]I keep saying synonyms biological source family and your classification. If we remember these four points, then the links to many questions remain hidden here.

[00:01:15]Its answers are hidden here.

[00:01:17]Like licorice which is called liqueur. The biological source of liquefaction is glabra i.e. Glycyrrhiza glabra and from the same Glycyrrhiza, glycerin is obtained, which is the correct answer here. Ok? clear?

[00:01:30]So licorice is known as ST. Glycyrrhiza glabra is the biological source.

[00:01:34]Belongs to the Leguminaceae family. Yes.

[00:01:36]What do we do with it as an expectorant? Let's use it. In The Structure of Cardia Glycosides.

[00:01:42]You must have read the structure of cardiac glycoside.

[00:01:44]So what you people must have read is that sir you have four rings. This ring is A and this ring is your V which is your what? There is a mirror. And after that what is your ring C?

[00:01:59]G is trans. And what is the ring D that you have with it?

[00:02:04]These two D rings of yours are C and D Cs. A and B are cis.

[00:02:09]B and C are trans. Isn't that it? So Sir Ring and B C and D R Sis. It is A B C.

[00:02:16]C is D Cs. and while ring BCR Trans. What is B and C? Trans happens.

[00:02:21]Option number A is student correct.

[00:02:23]Sniper J Double E 19 has a question. So you guys must have read the structures of cardinolite buffered cardinolites. And in those structures, you guys must have noticed that Sir A and B are sis. C and D are cis.

[00:02:34]While what are B and C? are in the form of trans. This is an easy question.

[00:02:41]Questions were asked from Direct Class Apna Structure. The enzyme present in bitter almond. What enzymes are present in bitter almonds? Bitter almond which is a cyanogenetic derivative glycoside. By being crazy BB, I tricked you into remembering what Bitter Almond and Wild Cherrybark are?

[00:02:57]Come under cyanogenetic. What enzyme is in it? Is it papain, emulsin, streptokinase or L-asparginase? So sir, basically remember that winter almonds contain emulsin enzymes.

[00:03:07]This is the question from a student of Sniper J Double 24. You have to remember directly what is inside it, sir? Contains emulsins.

[00:03:13]Belongs to Rosies family. Prunus amygdalus is the biological source of Prunus caminis. Sweet almonds and amygdalin are the chemical constituents of these.

[00:03:23]What are the students saying? Are present. Yes. Ok? Next question is what is Biolgit test used for, so you must have read Killer Killiani test, Legal test, Biolgit test, Raymond test, Renault test, KD test. What are all these tests for? So sir, all these tests that I just told you, what are they done for your cardiac glycosides? Students are used to identify them.

[00:03:45]That means Sir, this is also a question of Sniper JWE23 and it is very simple that Sir, this cardiac glycoside option number B student will be correct here.

[00:03:56]Remember the form test for saponin. You can see the queries from the form index that is created for you.

[00:04:01]When we talk about anthraquinone glycoside or anthracene glycoside, then sir, what are the modified bond triple test, bond triple test, such question tests that you get? Can be seen. Yes. So these are your biology test, KD test, antimony trichloride test, Raman test, legal test, clear cliani test, you have to remember the appearance of all of them. And I had also told you about the chemical identification test through a trick and made you remember it.

[00:04:26]You have to remember it well. Queshia Belongs to the Family. To which family does Quesia belong? This is the question of Sniper JW 2023. So I told you who filed the case brother? Seema did.

[00:04:39]On whom? On Reshma. So Seema will become Seemaru BAC family.

[00:04:44]Picreshma excelsa will become a biological source from silk.

[00:04:46]Why? Because the relationship had become bitter.

[00:04:48]WITTER WOOD What's with it, sir? Synonyms. So this is what you have to do. This is what you have to do, sir. Simaru, what will happen to you like that? It will become a family.

[00:04:57]Seema had filed the case. Simaru is also such a family.

[00:05:00]On whom? On Reshma. Pic Resham Excelsa Biological Salt. Because the relationship had become bitter.

[00:05:07]We consider it under the synonyms of Winter Wood. Yes. So look Sir Witherwood and Jamacashia what's with it? Synonyms. So they will apply these mnemonics, they will apply tricks.

[00:05:16]You will easily solve the questions there. Yes.

[00:05:18]Sinigrin is which type of glycoside? In which is Seeni Green present? So I gave you a mnemonic for this as well. However, sinigrin is present inside S glycoside.

[00:05:30]This chemical constituent is present in black mustard.

[00:05:34]What would you have done to these isothiocyanate derivative glycosides? Must have discussed.

[00:05:36]And I had reminded you that have fun and stay happy, that is, your mustard i.e. black mustard is an isothiocyanate derivative track, if you do n't have too much fun then life will become crucial, it belongs to the Cruciferae family, where did you go to have fun, you went to Brazil, Brassica [ __ ] is its biological source and sir, what did you do while having fun, you started vomiting a lot, it is known for its emetic property, have fun but don't do sin, sin means don't commit sin, so from sin, sinigran became its chemical constituent.

[00:06:09]I have told you all this in the story, sir. So your correct isothiocyanate derivative what is your sinigran? G is a glycoside.

[00:06:17]Black mustard is found in isothiocyanates.

[00:06:19]Sinigrin present in black mustard is used as a chemical constituent. Pharmacological activity of glycosides is due to what? The pharmacological activities of glycosides are due to what?

[00:06:33]Glycone part, aglycone or both parts. So you must have read that sir glycosides are complex organic compounds. And two things are present in complex organic compounds.

[00:06:42]Glycon and aglycon. Glycons are basically what your sugar part is called.

[00:06:49]Who has what? Has water solubilities. And what happens near the aglycone part? So all of this has a therapeutic effect. So what will be the student's correct answer here? That is the aglycone option number B.

[00:07:01]What does a glyconematologist have a head for? These activities can be seen. G Chemical Test of Cardiac Glycosides What is the chemical identification test of cardiac glycosides? What is G chemical test?

[00:07:14]Killer Kiliani Test, Bond Trager Test, Meyer Reagent Test, Dragon Drop Test.

[00:07:19]So you must have read about Dragon Drop Test, Mayer Reagent Test. What are all these basically used for? Used for alkaloids.

[00:07:26]Bond trigger test, modified Bond trigger test, is used for anthracene glycoside. So sir, what is left now? Killer Cliani Test. So what are all these things like Kiliani test, Legal test, KD test, Welzigt test, Raymond test for? Your cardia is for glycosides. Isn't it? Isn't it? And the Killer Killiani test is used to identify Sir Digitoxose.

[00:07:49]Sniper JWE 2021 question. So in NIPER you will get many questions from glycoside and you can solve them easily.

[00:07:58]What is called bitter glycoside? G Bitter Glycoside means Miscellaneous Glycoside.

[00:08:02]And I reminded you of the example in Miscellaneous Glycosides. Henna, Kalmek, Gymnema, Picrorhiza, Serrata, Quassia, Jasion. I had given this example of miscellaneous glycoside which is known as bitter glycoside.

[00:08:14]Naipoz Double 18 question is student.

[00:08:16]So what are Sir Bitter glycosides? Is it Andrographis, Ashwagandha, Shankhapushpi or All of the Above? Tell me what will be the correct answer? So Sir Andrographus, your correct answer will be here. Yes.

[00:08:29]Who is called Andrographis? Kalmegh.

[00:08:32]Kalmegh's Kirayat, Bhuiniv, Andrographus.

[00:08:35]What is this about? That is your synonym of Kalmegh.

[00:08:40]So Sir Kalmegh comes in better glycoside. What will happen to Option Number A student? It will be corrected.

[00:08:46]Ok? So Sir Kalmeg remember synonyms are andrographus. This is basically Andrographis paniculata, your biological source. Belongs to the Canthaceae family.

[00:08:56]Bond trigonal test is used for identification of.

[00:09:00]I just cleared Bond Triangle Test and Modified Bond Triangle Test. This is a question from Sniper J Double 10, student.

[00:09:06]Anthraquinones, alkaloids, steroids and terpenoids. What will happen? Correct Answer Bond trigger test is used for identification of anthraquinone, alkaloid, steroid or terpenoid. So Sir, modified Bond trigger test and Bond trigger test are seen in Bond trigger test, anthracnose glycoside, anthracene glycoside. Yes. Isn't it? So what will happen to option number A student here? It will be corrected.

[00:09:29]You also have to remember the color. Ammonium layer, pink, red color appear to you.

[00:09:35]Which of the following are acid resistant glycosides? Which of the following are acid resistant glycosides? Yes, this is a question from Sniper J Double 2003. O glycoside, N glycoside, C glycoside, S glycoside Acid resistant What happens to you? C contains glycoside. What is a student? Remember directly that C glycosides come under acidic resistant glycosides.

[00:09:57]And what would you have read about in C glycoside? So in C glycoside you must have basically read about Aloe Cascara and Cochineal. By saying ACC I am able to remember that Sir, there is one C i.e. one cement of ACC brand. Okay, right? The cement of ACC company is good. So C for C glycoside, C for cement and ACC for alloy cascara and catchaniol will be your drug.

[00:10:17]So let's remember it this way.

[00:10:18]ORS Rubv becomes army. The N glycoside is in the nucleoside. S glycoside isothiocyanate i.e. your black muster known as signin.

[00:10:27]So you have to remember all that.

[00:10:29]You will be asked questions from the example in the NIPERS exam. Wild Cherry Wild Cherrybark Contains Which Type of Glycosides? What does wild cherrybark come in? Saponins, flavonoids, isothiocyanates or cyanophore glycosides?

[00:10:43]So I reminded you and gave you a trick. I had given a trick called Sun's wife, cyanogenetic, cyanophoric, so who is Sun's wife, wife means bitter almond and wild cherry bark, what are these, they are crazy, they belong to the Rosaceae family, I had also told that Sun's wife is not agreeing with Rose, she is saying take me for a walk, so Qualia, your bitter almond, wild cherry bark, what is the family of all three, it is Rosaceae family, okay, so sir, what will be there in cyanophore glycosides, which will be considered in wild cherry bark saponin, so sir, your momordica, ginseng, gokhru, shatavari, discorea, white musli, liquida, senega, Qualia, brahmi, these come under saponin, in flavonoids, I have made you remember citrus plants, gingko, I have made you remember buckwheat, I have made you remember silymarin, in isothocyanate, so sir, there is only one glycoside, that is the black mustard, I have made you remember this, so all the classifications should be absolutely on your tongue and I have mastered the classification very well I have already made you remember it very well with a good mnemonics trick, please remember it. Cenocysts mainly contain which glycocytes?

[00:11:49]What are mainly present in cenocytes?

[00:11:51]What are mainly present in cenocytes? Which glycosides are present? Terpenoids, steroids, anthracnones or triterpenoids inside the cenocytes.

[00:12:01]What will the cenocytes present? Yes. So Sir, there will be a presentation inside the army and what is the army?

[00:12:05]G is anthracene glycoside.

[00:12:08]What have you read about anthracene glycoside? So Sir, we have reminded you of these examples: Rubus, Cascara, Senna, Cochineal, Aloe, Hypericum.

[00:12:15]So sir, what will be the correct answer here? Anthracnones. Okay, right?

[00:12:19]Sennosides ABC and C are the chemical constituents present in senna. And in which army does that army come? So sir anthracnone comes under the examples of glycoside.

[00:12:28]Apart from Senna, Rubus Cascara, Cochineal, Hypericum, Aloes all come under Anthracene.

[00:12:34]Anthracene has two moieties.

[00:12:35]Anthracnone and anthranol are two different compounds. Isn't it? Let's see what are the substitutions in cenocytes A and B at the third position?

[00:12:46]This time students were asked questions on their structure. This is also a question of NAPER JE 2019. And you will get these types of questions in snipers. Okay, right? So sir substitution incenocyte A and B at third position. The RCOH carboxylic group is at the third position.

[00:13:00]CHOH, OH or C C CH group is present. So sir, carboxylic group is present. Sennoside When we talk about A and B, at the third position, sir, we see the carboxylic group there, option number A here.

[00:13:15]Ok? So remember, sennoside A is your carboxylic group. In C and D CH2OH is present.

[00:13:21]What are these transmissoforms?

[00:13:23]You get to see the structures. Alloy contain which type of glycoside?

[00:13:28]Which glycoside does aloin have? I just reminded you now.

[00:13:30]I just told you.

[00:13:32]You might have read it also.

[00:13:34]All of you are qualified Jeepat and the qualified Jeepat sir, all these drugs are already on their tongue. There is no need for too many explanations.

[00:13:43]Absolutely. Sir nucleoside will come in N glycoside.

[00:13:44]ORS i.e. Rubv Sena will come in O. Sir Eloy Cascaras Cochonial will come in C. Sir, what will happen to you if cigarette comes in this? Will the student come under C Alloy Cascara Quotient option number C? Ok? Let's move on to the next question. In diosgenin the type of ring present in the structure is in diosgenin. Diogenin has a the type of ring present in its structure.

[00:14:12]What type of ring is present in diosgenin?

[00:14:14]Phenanthin, andol, steroid or midazole, what type of ring is present in diosgenin, G saponin derivative saponin is being discussed, where is diosgenin present here, hecogenin diosgenin are all present in saponin and what is saponin, G it is of steroidal nature, steroidal ring is present, option number C student what will be done here will be correct, G licorice belonging to V family licorice, licorice is being talked about, G licorice licorice is being talked about, Glycyrrhiza glabra, Glycyrrhiza glabra is its biological source.

[00:14:48]Sir is known for its expectorant properties.

[00:14:50]And I reminded you that people used to drink liquor. Where did the Leguminosae go? Fabaceae Leguminosae What will happen here sir? The correct answer will be option number D. Ok? So, these are the family points. Which of the following phytoconstituents is used for peptic ulcer?

[00:15:10]What phytosubstitute is used for peptic ulcer? Seena Alloy Safed Musli Aquarice Which one do we use? For peptic ulcer, you must have read about H2 block drug, proton pump inhibitor, anti- cholinergic drug. Must read prostaglandin analogs. Must have read antacid. Ulcer protective ulcer healing and anti-H pyorrhea drugs, when you talk about pharmacology there, you must have discussed it there.

[00:15:34]Here we are talking about natural drugs.

[00:15:37]So students, remember sir, who owns these properties? So sir, these properties are owned by Lecheris.

[00:15:43]What are these, along with expectorants? So sir, it is used in peptic ulcer. Yes.

[00:15:47]Okay, right? These carbons are present in it and are used as an anti-ulcer drug.

[00:15:52]Okay, right? Carbenone sodium is used as an ulcer healing agent. It happens, right?

[00:15:58]You must have read it in drug classification. Which statement regarding diosgenin is correct? Here are four statements related to diosgenin.

[00:16:04]Student. Which statement is correct? This has been asked of you. This is a question from Sniper J Double 2019.

[00:16:11]Diosgenin is the hydrolytic product of the saponin dioscin. It is not the chief excipient of dysuria. It is a saponin glycoside both A and C. Tell me what is diosgenin sir? Saponins are present within the glycosides.

[00:16:24]This should be clear to you. Sir Option No. Diogenin is the hydrolytic product of the saponin. Yes sir is a product of saponin and saponin comes under glycoside. This is also clear. Both your points are correct.

[00:16:36]Yes, it's okay, right? Diosegenin is included in saponin glycosides.

[00:16:38]G Andrographolite It is obtained from Butch Kuruchi Kalmegh Wild body. Andrographolite What is Andrographus called? I reminded you that it was cloudy yesterday. Cloud means rain. So yesterday it became cloudy in Andhra.

[00:16:55]Andhra means andrographolite. The tenants who were sleeping on the ground got troubled. Bhui Neev is also its synonym. Kirayat is also its synonym. To have or not to have? So sir, what will happen to you here? Kalmegh Kalmegh happened in Andhra.

[00:17:10]Sir, option number C will be correct here. Isn't it? Andrographis paniculata is its biological source.

[00:17:16]Andrographolite is one of the chemical excipients present in them. All of this has to be remembered by doing Andhra. Yes. Chemical constituents of wild cherrybark Chemical constituents of wild cherrybark What would be present in wild cherrybark Amygdalin Hesperidin Prunasin or Picrasmin See there are two wild cherrybark and bitter almond Amygdalin is present in bitter almond Where is amygdalin present in bitter almond Where is prunasin present in wild cherrybark ok right amygdalin bitter almond bitter almond A for almond and A for amy remember and prunasin in wild cherrybark ok right so if we take BB on full moon night then BBV means wild cherry full moon that is prunasin ok let's come to option number next student next options what is the next question so kutki is synonyms for kutki what is called yes what is called kutki is a question from Nipper J Double 2006 synonym of glycoside is Nagarmotha Plus Opium Papi Picorhiza So Sir what is Picorhiza called? It is called Kutki.

[00:18:24]Ok? So sir what is option number D picorrhiza called sir? It is known by the names of Indian Gensian and Kutki.

[00:18:31]Ok?

[00:18:33]Alpha 17 unsaturated lactone ring is present in the following class of compounds.

[00:18:38]Alpha 17 unsaturated these cardinolite buffered cardinolite rings we're talking about.

[00:18:43]Who are you talking about? Talking about cardinolites and buffardinolites ring.

[00:18:47]Talking about cardio glycosides.

[00:18:49]Digitalis School Digitalis Stramodium Digitalis Silymarin Digitalis Amygdalin Sir not Amygdalin not Silymarin not Stromonium then what will happen Sir Correct Answer Inside Digitalis and School you will find this at 17 positions, at beta positions you will find the lactone ring, that student. Yes, let's move on to the next question. Family of Kalmegh Yesterday Kalmegh happened in Andhra, so the tenants who used to sleep on the ground got very upset and when Kaal Chaata happens then people feel lonely, Ekathiyasi where has Ekathiyasi gone brother, does option number D belong to Ekathiyasi family, yes, right, when Kaal Chaata happens then people feel lonely, I made you remember, you feel alone, this is a question of Sniper J Double E, if you apply the tricks, your question will be solved. There is nothing to be done and it will be solved very easily. There were no questions from glycosides in GPAT in 2026. But it is not that questions will not come in Sniper.

[00:19:53]In sniper, the question will definitely come from the student and this type of question will come and you will solve it very easily because I know that you have followed the tricks very well. For the killer, that means test. 40 killers killed me brother.

[00:20:07]Whose brother? 40 means digitalis. So alloy digitoxo diogenin both A and B, so sir what will it be, 40 killer killed 40 means what do I call digitalis tellis 40, so 40 killer means sir for whom will it be for digitoxoise, for whom will it be for digitalis, the chemical excipient of digitalis is digitoxoise, so sir we will use it for that only, so these are your tests, sir all this is for that only, these chemical identification tests are used for your cardiac glycoside, test reagent in Lieberman Barchard test, what test reagent is used in Lieberman Barchard test?

[00:20:46]What test reagents do we use at Lieberman Burchard?

[00:20:48]Concentrated sulfuric acid, dilute HCL, acetic anhydride both A & C.

[00:20:54]Test reagent in Lieberman Bachal test.

[00:20:59]What do we use inside the Lieberman Burchalt test? So what do we do with acetic anhydride? Let's use it.

[00:21:04]Known for its pink color. What is the appearance like? Is there a pink colour? So sir how do we get the color? Pink colour is obtained by Lieberman Bachalt test, remember it, saponin glycoside contains lactose form test, haemolytic test, Lieberman Bachalt test, what do we do with all these, we use them, Cascarocyte A is an example of Cascarocyte, it is the chemical constituent of Cascara, g Cascarocyte A B C, you must have read all this, Cascara which comes under anthracene glycoside and Cascara is such a drug, students, which you have to remember, which comes under both C and O glycoside.

[00:21:39]Cascara comes under whom? C & O glycosides come under both.

[00:21:44]So where did you go brother? C & O option number D will be corrected here. Yes. Cascara falls under both C and O. Remember this.

[00:21:51]Okay, right? However, we consider it only in C glycoside.

[00:21:55]Where do we store Aloe Cascara Cochineal? In C glycosides. But they also come under O glycosides. So Sir Cascara contains both C and O glycosides. Ok? Questions have also been asked from here in GATE. Yes. Dioscin steroidal saponin glycoside of Dyscorea tuber after hydrolysis gives when dioscin which is your steroidal saponin glycoside of Dyscorea or Discorea which is called Discocidea deltoidea Discorea deltoidea biological source, you know it by the name of Yam root, right, so sir tell me what will it give after hydrolysis, diosine + 3 glucose diosine + three rhamnose diosine plus two glucose plus one rhamnose diosine plus one glucose plus two rhamnose, student what does the diosine of Dyscorea give after hydrolysis, so remember that sir diosine plus one glucose plus two rhamnose you get to see this there.

[00:22:54]Ok?

[00:22:57]Penox Penoxa diol is a quastuent of Penoxa diol which is a quastuent of? Yes, in which one will you be present?

[00:23:05]In ginger, in jat mansi, in ginseng or in pepper? So you must have read that Sir, this is Ginseng Panax, whose Ningin Panax is this Sir?

[00:23:17]These are synonyms of Jinsingh. Panax and Ningin: Sir, you have to remember that Sir Panax Diol is derived from Sir Panax only.

[00:23:27]So what will happen to option number C student? It will be corrected.

[00:23:31]Sir, these are present inside Jinsingh.

[00:23:33]Panag is known as Ninjin. Okay, right? Gynocysts, panaxocytes, chikose susponins are present inside you.

[00:23:42]G. The quisitive of cochineal.

[00:23:45]What is present inside cochineal? Yes, this is your last question.

[00:23:51]What are present inside cochineal?

[00:23:53]Canthadine, hirodine, tannic acid or carbonic acid. So what did Sir Coach have? The coach was of a colourful temperament. Used as a colouring agent.

[00:24:02]And what did the coach have, sir? There was a red colored scale. So it is known as red scale insect.

[00:24:09]Synonyms. And cochineal is the only glycoside you can obtain from an animal source. It is caused by insects.

[00:24:17]Remember this also. Another property of Kochaniel is that Sir Koch had a car.

[00:24:22]Car means carbonic acid.

[00:24:26]How will it look with red colored water? It will give red color. Isn't it? So sir what will be option number D student? It will be corrected. It is basically used in cosmetics etc. It is used in lipsticks etc. As coloring agents. So what did I make you do with all these points from the car, i.e. from the coach to the coach? The students were made to remember. What all these points did I get you to tell the coach? I had you remember me. So this total important 30 questions in your ongoing series Sniper 360 was completed with glycoside. I made it a little faster because you have to maintain this speed.

[00:24:57]Where? When you go to give the sniper exam.

[00:25:02]I must have solved these 30 questions in around 25 minutes.

[00:25:05]You have to solve it at this speed. And it may also take more time.

[00:25:10]But basically what is it, it is a direct question. If you apply tricks and solve the question directly then it is sufficient. Isn't it? In the next class, I will get you to solve 30 important questions of the remaining topics of Pharmacology.

[00:25:23]See you students in the next class with the next concept. Thank you everyone for watching GDC and supporting GDC. Thank you. Have a nice day student.
