How to study Pharmacognosy for GPAT?

Pharmacognosy is one of the core subjects of pharmacy curriculum and to crack GPAT with high percentile it is mandatory that a student must study this subject in detail. Here, I am giving you some worthy tips on how to study Pharmacognosy for GPAT to qualify the same with flying rank.

GPAT is the online national level exam conducted by AICTE to facilitate the admission into M.Pharma course by B.Pharma students. Every year around 40000 thousand students take this test to test their knowledge but very few of them are lucky enough to make through this exam with a very high rank. The whole GPAT revolves around four core subjects- Pharmaceutics, Pharmacognosy, Pharmacology and Pharmaceutical Chemistry. Out of these four subjects, Pharmacognosy is the most scoring and easy to prepare in my own perception and analysis. I am saying this on the basis of my own personal experience.
If you are planning to prepare for GPAT and don't know how to prepare for GPAT then I strongly recommend you to start with Pharmacognosy as it will take lesser time and will provide more fruitful result. Now, I am coming to the main theme of the resource.

Important topics to be covered for GPAT in Pharmacognosy

Although, it is difficult to point to certain topic which should be covered in Pharmacognosy but still I have extracted some hot topics from the Pharmacognosy from which every year plenty of questions asked in the GPAT. Here I am giving the detail of these topics with guidance for how to study them?

Important drugs to be studied in Pharmacognosy for GPAT

When I prepared for the GPAT exam, I made a list of around 30 important drugs which are asked most of the time in GPAT exam. Here I am sharing these drugs with you. But before giving you the name of these drugs, first I must tell you that what should you study in these drugs? Whenever you start study a drug divide it into following parts- Biological source of the drug, microscopy of the drug, chemical constituent of the drug and chemical tests of the drug. These are the four must read parts of any drug you are going to study. Make notes of these drugs while studying them as it will help you in the revision. Now I am hiving the list of most important drugs in Pharmacognosy for GPAT.
Important glycosides to be studied for GPAT- Digitallis, Senna, Aloe, Liquorice, Dioscera and Ginseng.
Important alkaloids to be studied for GPAT- Ergot, Vinca, Opium, Atropa, Kurchi, Cinchona, Ephedrine and Physostigmine.

But, I must tell you that this single topic is the secret to achieve high rank in the GPAT as there are lots of questions asked in the GPAT from this section and not much of the student pay attention to this topic.

Weightage of Phytochemical screening in GPAT

Phytochemical screening is another hot topic which carries high weightage in the GPAT exam. While studying phytochemical screening of the drugs you must study the name of test, reagent used in it and the result obtained. The Imortant chemical classes which should be studied in the section for GPAT include Alkaloids, Glycosides, Tannins, Flavonoids and steroids. But I recommend you to study the whole section in detail as it is not too much long but carry high weightage.

All of the sections are dealt in detail in this book. But, still you are interested in other book then you can go for Trease & Evans as this book also have great content for GPAT exam.
