This book consists of an introductory overview of metabolites of plants and deals with their Types, Classification and Uses. Emphasizing on Secondary metabolites like the Phenolics, Terpnes and nitrogen containing Compounds. The first section would cover the structure, Classification and biosynthetic pathways for the synthesis of these Secondary metabolites in plants and their uses and advantages. The next section would include the isolation techniques of secondary metabolites, Methods of Large-Scale production and lastly the Biotransformation, which are upcoming and thrust areas in the field of pharmaceutical industry which explores and puts to use the therapeutic potential of different secondary metabolites present in plants. Also, the techniques for their isolation is important with the point of view of framing research work including its analysis qualitative and quantitative parameters for students. Last Section would include the other sources of secondary metabolites like microorganisms and Knowledge about medicinal plants. The chapter emphasizes on occurrence and types of different metabolites in different microorganisms and their isolation techniques and uses. To conclude with the Knowledge of medicinal plants and the presence of various metabolites in them and their applications in various disease and ailments. This Book will Benefit the students of both Under Graduate and Post Graduate programs and Research Scholars of all the streams of Life sciences like Botany, Biotechnology, Zoology, Microbiology, Biochemistry and Pharmacology. The students pursuing research could use the book which include isolation techniques and genetic engineering methods relevant to plant secondary metabolites to prepare frame work for methodology of their research work.
