ABSTRACT
Objective To establish the quality standards system of A system to multiple evaluation on Yinxing huonao capusle,and discuss the feasibility of the method whether A system to multiple evaluation to be used for traditional Chinese medicine quality standard.Methods Identification of the Yinxing huonao capusle by TLC method was established by one thin layer chromatography system.HPLC was used to detect 6 types of the primary active components in Yinxing huonao capusle.Results 5 types of the primary active components were synchronize identified by one thin layer system.The color of spots was clear and had a good separation effect.6 kinds of the primary active components were synchronize detected by one system with high accuracy.Conclusion The established method A system to multiple evaluation can be used for the study of the quality standards system of Yinxing huonao capusle.
ABSTRACT
Objective To explore the extraction process of Yinxing Huonao capusle.Methods Central composite design-response surface method was used to optimize the extraction process with quantity of water and boiling time as main factors and with syringin transfer rate,emodin transfer rate and solids retention rate as evaluation index.Results The conditions of the optimized extraction process were as follows:10-fold water,extracting time of 160 min,extracting 2 times.Conclusion It is feasible that central composite design-response surface method is used to optimize the extraction process of Yinxing Huonao capusle,and the optimized extraction process is simple and reliable.
ABSTRACT
Objective:To establish the quality standard system of Gui Erbai gel based on a method ofa system to multiple evalu-ation and discuss the feasibility of the method used for the quality standard for traditional Chinese medicine. Methods:TLC identifi-cation of Gui Erbai gel was established by one thin layer system. An HPLC method was used to detect 6 active components in Gui Erbai gel. Results:Five active components in the gel could be identified by one thin layers system simultaneously with clear spots and good separation. Six active components in the gel could be determined by the same HPLC system with high accuracy. The average content of podophylotoxin,quercetin,kaempferol,imperatorin,dictamnine and rutin is as follows 0. 154,0. 052,0. 138,0. 051,0. 060,0. 048 mg· g-1 . RSD<3％. Conclusion:The established method based on a system to multiple evaluation can be used for the quality standard establishment for Gui Erbai gel with the properties of promising feasibility, simple operation, low cost, high accuracy and good stabili-ty.
