RESUMO
Components of volatile oil in differently processed products of Vitex trifolia var. simplicifolia Cham. were analysed with GC-MS-computer method. Results showed that content of volatile oil was decreased and its quality changed after processing. A total of 26 components were identified. There were 26 in raw sample,26 in slightly roasted sample,20 in burnt sample and 16 in charred sample.
RESUMO
AIM: To establish the method for quality control of Yijingbushen Granules(Herba Epimedii, Semen Cuscutae, Radix Paeoniae Alba, Rhizoma Curcumae, etc.). METHODS:Semen Cuscutae, Radix Paeoniae Alba and Rhizoma Curcumae in this medicine were identified by TLC; The content of icarrin in this medicine was determined by HPLC;The acetonitrile-2%acetum(30∶70) solution was used as the mobile phase. The flow rate was 1.0mL?min -1. The detection wavelength was set at 270nm. RESULTS:Semen Cuscutae, Radix Paeoniae Alba and Rhizoma Curcumae, could be identified by TLC on lichrospherC 18 column. For Icarrin, the linear range was from 4.32 to 21.60?g, and the average recovery was 98.69% with RSD of 1.13%. CONCLUSION:The method is simple, reliable, accurate and can be applied to the quality control of the preparation.
RESUMO
To evaluate the internal quality of prepared pieces of Radix Sanguisorbae combinatively, the characteristics comparision, content determination of aqueous extract and tannins,and coagulation experiment of 10 prepared pieces of it on the market have been carried out. Based on these studies, it is the best to use the crude one in compound Chinese medicines. But its original property must be retained if it is baked into charcoal for use. The quality standards of Radix Sanguisorbae and its processed product into charcoal were also described.
