  <dc:description xmlns:ns0="xml" ns0:lang="en">The current importance of drugs of natural origin and their different phytotherapeutical preparations are mentioned. Analytical aspects related to vegetable drugs and their extracts are discussed. An overview is given on procedures used for the isolation of reference compounds, sample preparation for high-performance liquid chromatographic analysis, identification of vegetable drugs and detection of adulterants. The different approaches currently employed for the standardization of extracts are presented. The various aspects are discussed with the aid of illustrative examples.</dc:description>
