OBJECTIVE To introduce the definition and determination of biological potency and process in the application in drugs of biochemicals, chemicals and herbs, and to provide ideas and references for studying the quality control of drugs. METHODS Describe the basic concepts of biological potency, including definition, classification and standard of determination, and detection ideas. Emphasize on the wide use of the application in drugs of biochemicals, chemicals and herbs. RESULTS AND CONCLUTION It is illustrated the importance of determination of biological potency as a routine analytical tool in quality control of drugs in the future. The model of combination biological potency detection with chemical analysis is a powerful tool for drug quality control.
