摘 要:目的:建立高效液相色谱法测定血塞通胶囊中三七皂苷R1、人参皂苷Rg1、人参皂苷Rb1的含量方法;方法:色谱柱为Di-amonsil C18柱(5μm,250mm×4.6mm);乙腈-水线性梯度洗脱;流速:1.0ml.min-1;检测波长:203nm;柱温:30℃。结果:三七皂苷R1、人参皂苷Rgl和人参皂苷Rb1的线性范围分别为2.555~12.775μg、8.125~40.625μg和7.665~38.325μg,相关系数分别为0.9996、0.9999和0.998,平均加样回收率(n=6)分别为99.2%、99.8%和99.5%,RSD分别为0.52%、0.28%和0.45%。结论:本方法具有简便、快速、准确等特点,可用于血塞通胶囊的质量控制。Objective: The method for the determination of notoginsenoside R1, ginsenoside Rgl and ginsenoside Rbl in Xuesaitong Capusle was established. Methods: The separation was performed on Diamonsil C18 column (5μm,250mm × 4.6mm) , The mobile phase consisted of acetonitrile (A) - water (B) with Linear gradient elution ; at a flow rate of 1.0 mL· min^- 1 ; the warelength of detector was 203 nm ; the column temperature was 30℃ . Result: The calibration curves showed good linearity in the range of 2.555 - 12.775μg (notoginsenoside R1 ) ,8. 125 -- 40. 625μg ( ginsenoside Rg1 ) and 7. 665 -- 38. 325μg ( ginscnoside Rbl ). The average recoveries rate ( n = 6) were 99.2% ,99.8% and 99.5% , RSD were 0.52% ,0.28% and 0.45% .Conclusions : The method is convenient,rapid,economical and accurate. It can be use for quality control of Xuesaitong Capusle.
