A Textbook of Pharmacognosy and Phytochemistry

ISBN: 978-93-93806-25-3

Pharmacognosy and Phytochemistry form the foundation for understanding medicinal plants and the naturally occurring chemical constituents responsible for their therapeutic effects. Since ancient times, plants have served as an important source of medicines, and even today many modern drugs are derived directly or indirectly from natural products. Therefore, a sound knowledge of medicinal plants, their constituents, extraction methods, and analytical techniques is essential for every pharmacy student.

This book has been prepared according to the latest B. Pharm syllabus and is designed to provide students with a clear and systematic understanding of the subject. The contents cover the fundamental concepts of metabolic pathways and the biosynthesis of secondary metabolites, including shikimic acid, acetate, and amino acid pathways. Modern developments such as pathway prediction tools and CRISPR/Cas9 technology have also been introduced to help students understand current trends in phytochemical research.

The book presents detailed pharmacognostic studies of important crude drugs containing primary and secondary metabolites, including carbohydrates, proteins, enzymes, lipids, alkaloids, glycosides, volatile oils, tannins, flavonoids, terpenoids, and related compounds. Conventional and advanced extraction methods, along with modern techniques for isolation, identification, characterization, and quality evaluation of medicinal plants, have been discussed in a simple and student-friendly manner.

Special care has been taken to explain concepts in easy language while maintaining scientific accuracy. Flowcharts, tables, illustrations, and examination-oriented questions have been included to facilitate effective learning and revision. The aim of this book is not only to help students succeed in examinations but also to develop a deeper appreciation of natural products and their role in healthcare.

We hope that this book will serve as a useful companion for B. Pharm students, teachers, and all readers interested in Pharmacognosy and Phytochemistry.
