Quality standard for Xuesaitong Granules / 中成药

ABSTRACT

AIM:To establish the quality standard for Xuesaitong Granule(total saponins of Radix et Rhizoma Notoginseng). METHODS:The contents of notoginsenoside R1,ginsenoside Rg1 and Rb1 were determined on the Shim-Pack C 18 (250 mm?4.6 mm,5 ?m) column,with CH3CN—H2O gradual elution and monitored at 203 nm. RESULTS:The average recovery of notoginsenoside R1 was 100.0% (RSD=1.00%,n=6),the minimum detection quantity cannot be lower than 5% labelled weight. The average recovery of ginsenoside Rg1 was 99.8 % (RSD=0.47%,n=6),the minimum detection quantity cannot be lower than 20% labelled weight. The average recovery of ginsenoside Rb1 was 99.8% (RSD=0.79%,n=6),the minimum detection quantity cannot be lower than 30% labelled weight. CONCLUSION:The method is simple,reliable,accurate and can be applied to the quality control of Xuesaitong Granules.
