ABSTRACT
Objective To establish a method of determining effective components in Tangzhiqing Capsule.Methods Gin- seng saponin Rg_1,Rb_1,Re and notoginseng saponin R_1 in the capsule were separated and purified by D_(101)macroporous absorption resin,and then determined by HPLC.Results The linearity arrange of ginseng saponin Rg_1,Re,Rb_1 and no- toginseng saponin R_1 were 1.88～11.28?g,1.76～10.56?g,0.294～1.764?g,0.752～2.256?g and the recov- eries were 101.51%(RSD=0.75%),100.58%(RSD=0.46%),100.29%(RSD=1.01%),98.64% (RSD = 0.73%)respectively.Conclusion The method is simple,feasible and reproducible,and can be used for the determination of effective components in Tangzhiqing Capsule.
ABSTRACT
AIM:To establish a method of determining effective components in Qianjin Shenanning Pills(Flemingia Philippinensis Merr.et Rolfe,Radix et Rhizoma Ginseng rubra,Radix et Rhizowa Notoginseng,etc). METHODS: The contents of ginseng saponin Rg_1,Rb_1 and notoginseng saponin R_1 were determined by HPLC. RESULTS: The four effective components could be separated and purified by macroporous adsorptive resins of D_(101) and n-butanol,and their contents could be determined. CONCLUSION: The method is simple,feasible and reproducibility is good,it can be used as quality control in medicinal preparation.
