Natural products are a rich source of bioactive compounds with a wide range of medicinal and clinical applications, which have been used for centuries as prominent medicines. These compounds and their synthetic analogs have shown interesting clinical results and gained substantial importance in recent years. Their importance is also growing with increasing concerns about the adverse effects of synthetic additives on human health and the environment. The increasing demand for natural products makes them especially important to the food, pharmaceutical, and cosmetics industries. Several natural products are routinely used as functional foods, ingredients in formulations, additives (colorants, antioxidants, etc.) or as final products (nutraceuticals and supplements). In several applications, consumers demand the substitution of synthetic compounds with natural ones since there is a widespread belief that natural products are effective and free from toxic effects. Therefore, the importance of natural products has seen a progressive and steady increase in recent decades. The first edition of the book titled Precise Chemistry of Natural Products and Heterocyclic Compounds was compiled to cover the syllabus of the subject ‘chemistry of natural products’ prescribed for BPharm course in most of the universities. In the present scenario, the subject has been removed from BPharm course prescribed by PCI but topics of this subject have been merged with other subjects in the BPharm curriculum. The second edition, titled Chemistry of Selected Natural Products and Heterocyclic Compounds has been updated with a comprehensive approach to cover the undergraduate and postgraduate courses in science and pharmacy. In pharmacy, the book will be helpful in the subject of chemistry of natural products (MPC 104T) while in science, the chemistry of natural products is taught as an independent subject or a part of organic chemistry. The book is divided into 14 chapters, covering the properties, biosynthesis, structural elucidation, activity, and uses of drugs. In most of the naturally occurring compounds, spectral data has been provided to increase the utility of this book. The chapter on ‘protein’ has been completely revised to cover the postgraduate syllabus in science and pharmacy.
