Abstract:
OBJECTIVE:To establish the quality standards of Pseudostellaria heterophylla.METHODS:P.cyclopeptides was identified by thin layer chromatography protosite reaction with ninhydrin reagent.The contents of moisture,total ash,acid-insoluble ash,water-soluble extract and alcohol-soluble extract were detected according to the standards stated in Chinese Pharmacopoeia.The content of pseudostellarin B was determined by HPLC.RESULTS:TLC identification of P.cyclopeptides and HPLC determination of pseudostellarin B were established preliminarily.Limitation of moisture content,ash content,extract and pseudostellarin B were defined.CONCLUSION:The qualitative method and quantitative method and physicochemical index can be used as standards for the quality control of P.heterophylla.
