Phytochemistry systematically illustrates, in addition to introduce the history of the plant chemistry, the status, progress and biosynthesis, the basic plant extraction techniques and methods of chemical compositions, as well as the utilization of new technologies such as nuclear magnetic resonance in the structural analysis of natural products. It also introduces the plant main chemical constituents' existence and distribution, structure and nature, extraction and separation, structure identification, pharmacological, biological activity and application. Using biosynthesis as the basic light source combining theory of germ, it aims to reveal the internal ties of certain components, and to introduce the modern biotechnology and organic synthesis in the application of research and development of active ingredients.
