This second edition retains the main objective of presenting organic chemistry and its compounds in an accessible and inviting way by linking it with the world of plants. Chemistry tends to be considered as a field that is hard to comprehend but the colours, fragrances, and defensive substances that plants produce and their uses serve as an introduction to chemistry. The book is a combination of organic chemistry with the living world of plants and an introduction to organic plant compounds for the non-chemist. The author, an organic chemist and plant enthusiast, has taught popular undergraduate college level courses on plant chemistry to non-chemistry majors and numerous field seminars to the general public. The comments and questions from these audiences and the topics that especially captivated them have greatly shaped this book. The book can be used both as a text to introduce organic chemistry as it relates to plants and as a text of reference for more advanced readers.
