The course covers the methods and techniques employed for screening medicinal plants for their bioactive constituents. It also discussed recent developments regarding methods of extraction, isolation, purification and spectroscopic identification of plant bioactive constituents. The following subject will be covered:
General concepts, medicinal plants information sources, phytochemical screening, screening for bioactive plant constituents, specific extraction procedures, applications of chromatographic separation techniques, characterization of the active constituents by physical and chemical methods. Application of spectroscopic techniques for identification of the isolated compounds and interpretation of their spectral data. The course also will deal with the different methods for evaluation of herbal products and drugs derived from them as started in the pharmacopeias. In addition, the methods of detection of foreign matters and impurities will be covered.
