Natural materials of plant, microbial or animal origin are an important source of modern drugs. This book deals with such materials with a focus on the pure, pharmacologically active compounds which can be isolated from them. The occurrence, biosynthesis, isolation, chemistry and medical use of the compounds are described, as well as semisynthetic derivatives and the use of naturally occurring substances as templates for synthetic drugs.
Thoroughly revised since the 3rd edition many chapters have been extended to reflect the increase in knowledge and information now available. This book should be of interest to undergraduate and graduate students of pharmacognosy, pharmacy, medicinal chemistry, phytochemistry, biochemistry and to all those who are interested in natural products.
