目的:通过对人参皂苷Rg_1的定性和定量的检测来控制固天泉胶囊的质量。方法:RP-HPLC法。以人参皂苷Rg_1为指标,测定固天泉胶囊中人参皂苷Rg_1的含量。采用Eclipse XDB-C_8柱(4.6mm×150mm,5μm),流动相:乙腈-0.5％磷酸水溶液(20:80),流速:1.0ml·min~(-1),检测波长:205nm,柱温:40℃。平均加样回收率为95.6％,RSD=3.1％(n=5)。结论:用本法测定固天泉胶囊中人参皂苷Rg_1的含量,操作简便,结果准确。
Objective: To control the quality of Gutianquan capsules by qualitative and quantitative detection of ginsenoside Rg_1. Method: RP-HPLC method. Ginsenoside Rg_1 was used as an indicator to determine the content of ginsenoside Rg_1 in Gutianquan capsules. Eclipse XDB-C_8 column (4.6 mm×150 mm, 5 μm), mobile phase: acetonitrile-0.5% phosphoric acid aqueous solution (20:80), flow rate: 1.0 ml·min-1, detection wavelength: 205 nm, column temperature: 40°C. The average recovery was 95.6% with RSD = 3.1% (n = 5). Conclusion: This method was used to determine the content of ginsenoside Rg_1 in Gutianquan capsule. The operation was simple and the result was accurate.
