Natural Products: Isolation, Structure Elucidation, History

Description

Written by experienced authors, this book presents numerous natural everyday products with a high range of structural diversity. Twenty natural products have been arranged in five sections, describing three alkaloids, five colored compounds, three carbohydrates and glycosides, seven terpenoids, and two aromatic compounds.
Adopting a highly didactical approach, each chapter features a uniform structure: Background, in-depth information about isolation processes and structural characterization as well as a Q&A section at the end. Alongside the theoretical information many practical hints for the laboratory work are also included. A comprehensive overview of UV-, IR- and NMR-spectroscopy as well as mass-spectrometry for every exemplified compound is provided and the understanding of these methods is supported by concluding questions and exercises.
Educating and entertaining, this full-color textbook turns the learning process into a real pleasure, not only for students in natural products chemistry but also experienced professionals.
