HPLC同时测定薏仁肠肽胶囊中人参皂苷Rg1和三七皂苷R1含量
摘要
目的:采用反相高效液相色谱法测定薏仁肠肽胶囊中人参皂苷Rg1和三七皂苷R1含量。方法:采用色谱柱为Agilent ZE-C18柱(4.6 mm×250 mm
5μm)
以乙腈-水(17∶83)为流动相
流速为1.0 mL.min-1
检测波长为203 nm。结果:人参皂苷Rg1在0.4~10.1μg呈良好的线性关系
r=0.999 8
三七皂苷R1在0.1~2.5μg呈良好的线性关系
r=0.999 8
人参皂苷Rg1平均回收率99.96%
RSD为0.25%
三七皂苷R1平均回收率100.03%
RSD为0.23%。结论:本法可同时测定薏仁肠肽胶囊中人参皂苷Rg1和三七皂苷R1含量
方法可靠、准确。
Abstract
Objective:To determine Determination ginsenoside Rg1 and notoginsenoside R1in Yirenchangtai Capsules by HPLC.Method:The separation was performed on Agilent ZE-C18 column
using methyl cyanide-water(17∶83)as mobile phase.The detection wavelength was at 203 nm.The flow rate was 1.0 mL·min-1.Result:The linear range of ginsenoside Rg1 was 0.4-10.1 μg(r=0.999 6)
The linear range of notoginsenoside R1 was 0.1-0.25 μg(r=0.999 6).The average recovery of ginsenoside Rg1 was 99.96%
RSD was 0.25%(n=6).The average recovery of notoginsenoside R1 was 100.03%
RSD was 0.23%(n=6).Conclusion: The method can determine the ginsenoside Rg1and notoginsenoside R1 The method was reliable and accura.
