【摘要】 目的建立愈伤灵胶囊中人参皂苷Rg1的含量测定方法。方法采用高效
液相色谱法。色谱柱为HypersilBDSC18柱(150mm×4.6mm,5μm);流动相:乙腈-0.5%磷酸溶液(24∶76);流速:1.0mL/min;柱温:25℃;检测波长:205nm。结果人参皂苷Rg1进样量在0.05~0.80μg内呈现良好的线性关系,回归方程为:Y=3629375.5X+2517.1,r=0.9998,平均回收率为100.48%,RSD=1.59%(n=5)。结论测定方法简便、准确、重现性好,适用于愈伤灵胶囊中人参皂苷Rg1的含量测定。 更多还原
【Abstract】 Objective To established a method for the content determination of ginsenoside Rg1 in Yushangling Capsules by HPLC. Methods HPLC was used with the C18 column. The mobile phase was acetonitrile-0.5% phosphoric acid (24∶76). The flow rate was 1.0 mL/min, the column temperature was 25 ℃, and the detection wave was set at 205 nm. Results The calibration curve was linear in the range of 0.05~0.80 μg. The regression equation was Y =3629375.5X+2517.1, r =0.9998. The average recovery was 100.48% and RSD... 更多还原
