摘要: 目的:建立人参归脾丸中人参皂苷Rb1的高效液相色谱(HPLC-UV)法含量测定方法, 以期为人参归脾丸的质量控制提供依据。方法:对人参归脾丸中的人参皂苷Rb1含量进行测定。色谱柱为 Agilent ZORBAX SB-C18(4.6 mm×250 mm,5 μm),流动相为乙腈(A)- 水(B),梯度洗脱,流速1.0 mL·min -1,进样量10 μL,柱温 25 ℃,检测波长 203 nm。结果:人参归脾丸中人参皂苷Rb1的稳定性和重复性试验的RSD分别为1.4%和1.6%。采用梯度洗脱得到的色谱图各色谱峰分离效果好,达到含量测定的要求。人参皂苷Rb1在19.27~963.59 μg·mL-1范围内峰面积对进样量线性关系良好(r=0.999 9),平均回收率为96.1%(RSD=1.8%,n=6)。3批样品测得的人参皂苷Rb1含量结果分别为0.265、0.271、0.268 mg·g-1。结论:该方法准确、简便、专属性好,可用于人参归脾丸中人参皂苷Rb1成分的含量测定,为人参归脾丸的质量控制提供依据。

Abstract: Objective: To establish the HPLC method to determine the content of ginsenoside Rb1 in renshenguipi pills,to provide basis for the quality control of renshenguipi pills. Methods: The content of ginsenoside Rb1 was determined by HPLC method.The Agilent ZORBAX SB-C18 column(4.6 mm×250 mm,5 μm)was used. The mobile phase consisted of acetonitrile and purified water was used in gradient elution at the flow rate of 1.0 mL·min - 1 and the injection volume of 10 μL. The column temperature was set at 25 ℃ and the detection wavelength was 203 nm. Results: The RSD of the stability and repeatability test of ginsenoside Rb1 in renshenguipi pills were 1.4% and 1.6% respectively. The separation effect of each chromatographic peak of the chromatogram obtained by gradient elution was good, which meets the requirements of assay.The linear ranges of ginsenoside Rb1 were 19.27-963.59 μg·mL-1(r=0.999 9).The average recovery was 96.1%(RSD=1.8%, n=6). The ginsenoside Rb1 contents of 3 batches of samples measured were 0.265,0.271,0.268 mg·g-1 respectively. Conclusion: The method is accurate,simple and reproducible, and can be used for the content determination of ginsenoside Rb1 in renshenguipi pills, which provides basis for the quality control of renshenguipi pills.
