ABSTRACT
AIM: To develop a method for determining contents of ginsenoside Rb_1,ginsenoside Rg_1 and notoginsenoside R_1 in Sanxue Mingmu Tablet(Radix et Rhizoma Notoginseng,Pheretima,Herba Leonuri,Rhizoma Imperatae,etc.). METHODS: The contents of ginsenoside Rb_1,ginsenoside Rg_1 and notoginsenoside R_1 were separated by gradient elution on Hypersil ODS C_(18) column(5 ?m ? 4.6 mm?100 mm) as stationary phase;acetonitrile and water as gradient mixed mobile phase;detected at 203 nm wavelength;(25 ?C) of column temperature and 1.0 mL/min of mobile rate. RESULTS: Ginsenoside Rb_1,ginsenoside Rg_1 and notoginsenoside R_1 had good linearities(r=0.999 9;n=6) at the ranges of 1.480 0-14.800 ng;0.372 0-3.720 ng and 1.072 0-10.720 ng.The average recoveries were 98.44%(RSD=0.96%);99.02%(RSD=0.94%);97.95%(RSD=(1.02%)),respectively. CONCLUSION: This method is high in column efficiency and satisfactory for isolation and repeatability,the result is accurate.It can be adopted for quality control of Sanxue Mingmu Tablet.
