摘  要:目的:建立以反相高效液相色谱法同时测定丹七片中三七皂苷R1和人参皂苷Rg1含量的方法。方法:色谱柱为Kromasil C18(250mm×4.6mm,5μm),流动相为乙腈-水-磷酸(20.5:79.5:0.02),流速为1.0mL·min^-1,柱温为室温.检测波长为203nm。结果:三七皂苷R1、人参皂苷Rg1的检测浓度分别在4.67-46.68(r=0.9990)、4.62~115.50μg·mL^-1(r=0.9999)范围内与各自峰面积积分值呈良好线性关系;平均回收率分别为97.93%和97.98%,RSD分别为1.31%(n=6)和1.38%(n=6)。结论:本方法简便、快速、准确.可用于丹七片的质量控制。OBJECTIVE : To develop a RP- HPLC method for the simultaneous determination of Notoginsenoside R1 and Ginsenoside Rgl in Danqi tablets. METHODS: The chromatographic separation was performed on a Kromasil C18(250mm × 4.6mm, 5μm) column with column temperature at room temperature. The mobile phase consisted of acetonilrile- water H3PO4(20.5 : 79.5 : 0.02) at a flow rate of 1.0mL ·min ^-1.The detection wavelength was set at 203nm. RESULTS: The linear range of Notoginsenoside R1 and Ginsenoside Rgl were 4.67-46.68μg ·mL^- 1 (r = 0.999 0) and 4.62-115.50μg ·mL^- 1 (r = 0.999 9), respectively; with the average recover of Notoginsenoside R1 at 97.93% and that of Ginsenoside Rg1 at 97.98%, and RSD at 1.31% (n =6) and 1.38% (n =6), respectively. CONCLUSION: The method is simple, rapid and accurate, and suitable for the quality control of Danqi tablets.
