高效液相色谱法测定脑灵口服液中人参皂苷Rg1的含量
Determination of Ginsenoside Rg1 in Naoling Oral Liquid by HPLC
【摘要】 目的:建立以高效液相色谱法测定脑灵口服液中人参皂苷Rg1含量的方法。方法:色谱柱为HypersilBDS-C18,流动相为甲醇-水(49∶51),流速为1.0ml/min,检测波长为203nm,柱温为30℃,进样量为20μl。结果:人参皂苷Rg1进样量在0.2μg~8.0μg范围内与峰面积积分值线性关系良好(r=0.9996),平均加样回收率为101.25%(RSD=1.54%)。结论:本方法简便、准确、重现性好,可用于本品的质量控制。
【Abstract】 OBJECTIVE:To establish an HPLC method for the determination of Ginsenoside Rg1 in Naoling oral liquid.METHODS:The assaying was conducted on a Hypersil BDS-C18 with methol-water(49∶ 51)as mobile phase.The detective wavelength was set at 203nm;the column temperature was 30℃ ;the flow rate was 1.0ml/min and the sample size was 20μ l.RE_SULTS:The linear concentration range of Ginsenoside Rg1 was 0.2μ g~ 8.0μ g(r=0.9 996);the average recovery was 101.25%(RSD=1.54%).CONCLUSION:The method is simple,accurate and reproducible;and it can be used for the quality control of Ginsenoside Rg1.
