Abstract:
OBJECTIVE To augment evaluation index, and establish a scientific and reasonable method for the content determination of Baibei Yifei capsule.
METHODS Samples were purified by C
18 column, optimized chromatographic conditions:Vp-ODS column (150 mm×4.6 mm, 5 μm); column temperature:20℃; fluctuan flow rate; the mobile phase acetonitrile (A)-water (B), gradient elution. The injection volume was 10 μL. The detection wavelength was 203 nm.
RESULTS The contents of notoginsenoside R
1, ginsenoside Rg
1, ginsenoside Rb
1 were linear in 40.24-241.44(
r=0.999 6), 91.50-549.00 (
r=0.999 9), 35.72-241.32(
r=0.999 8)mg·mL
-1, respectively. The recovery rate was 94.15%-99.81%, RSD was 1.12%-1.94%.
CONCLUSION The method is accurate and reproducible, which can provide the basis for the revision of the standard.
