摘要
目的采用HPLC梯度洗脱法同时测定保心宁胶囊中三七皂苷R1、人参皂苷Rg1、人参皂苷Rb1含量。方法采用ODS-C18柱,流动相为乙腈(A)-水(B)(0~12 min,A:19%;12~60 min,19%~36%;60~70 min,36%);检测波长为203 nm;流速:1.0 ml.min-1。结果三七皂苷R1、人参皂苷Rg1、人参皂苷Rb1的线性范围分别为0.764~6.365μg(r=0.9999)、0.633~5.275μg(r=0.9999)、0.699~5.825μg(r=0.9999),平均加样回收率分别为99.88%(RSD=0.55%)、99.97%(RSD=0.23%)、100.04%(RSD=0.15%)。结论该方法易行、准确可靠,可用于保心宁胶囊的质量控制。
Aim To determine notoginsenoside Rl and ginsenoside Rg1,Rb1 in Baoxinning Capsules by HPLC.Methods The ODS-C18 column was used.A mobile phase consisted of acetonitrile(A)-water(B)(0~12 min,A:19%;12~60 min,19%~36%;60~70 min,36%) gradient elution.The detection wavelength was at 203 nm.The flow rate was 1.0 ml·min-1.Results The linear ranges of notoginsenoside R1 and ginsenoside Rg1,Rb1 were 0.764~6.365 μg(r=0.9999)、0.633~5.275 μg(r=0.9999) and 0.699~5.825 μg(r=0.9999),respectively.The average recoveries were 99.88%(RSD=0.55%),99.97%(RSD=0.23%),and 100.04%(RSD=0.15%),respectively.Conclusion The method is simple,accurate and can be used for quality control of baoxinning capsules.
