Study on Quality Standard for Sanqi R Granules

Objective To establish the quality standard for Sanqi R Granules.Methods The Shim-Pack C18(250 mm×4.6 mm,5 μm) column was used,with CH3CN-H2O gradually elutied and monitored was at 203 nm,determined the contents of notoginsenoside R1,ginsenoside Rg1 and notoginsenoside R2.Results The average recovery of notoginsenoside R1 was 100.62%(RSD=2.99%,n=6).The average recovery of ginsenoside Rg1 was 99.01%(RSD= 1.91%,n= 6).The average recovery of notoginsenoside R2 was 99.66%(RSD= 2.38%,n= 6),the total contents limit of notoginsenoside R1,ginsenoside Rg1,notoginsenoside R2 shouldn,t be lower than 80 mg/tablet.Conclusion The method is simple,reliable,accurate and can be applied to the quality control of the Sanqi R Granules.
