Taking an interdisciplinary approach, Bioactive Compounds from Natural Sources describes general screening methods, HPLC hyphenated techniques, and NMR methods in the structural elucidation of compounds. Surveys on compounds displaying important pharmacological activities are presented in chapters devoted to Mexican medicinal plants, anti-tumor drugs of natural origin, cancer chemopreventive flavonoids, and metabolites displaying anti-HIV, antioxidative, antimalarial, and anti-inflammatory activity. The final chapters look at research into marine metabolites, covering immunomodulating marine glycolipids and surveys of bioactive compounds from marine opisthobranchs and Japanese soft corals.
