| Abstract: | Objective : Through determination of the dynamic change of the active component in different parts of Prunella vulgaris at different growth stages, to find the optimal harvest time. Method : Total flavonoids content was determined by using the spectrophotometric method, and the content of ursolic acid and oleanolic acid was determined by HPLC. The contents of ash and extract were determined according to the methods in Chinese Pharmacopeia (2005 edition). Result : There existed the active components in all parts of P. vulgaris, but the active component contents in different parts of P. vulgaris of at different growth stages, changed very obviously. Conclusion : In Yangtze-Huaihai region, the optimal harvest time of Prunella spike best harvest is at the end of June, and Prunellastem at the end of May. All parts of P. vulgaris have medicinal value. |
