摘 要:采用高效液相法测定参苓白术散中人参皂苷和甘草黄酮的含量,为下一步探究参苓白术散的体外抗氧化活性研究做准备。方法:采用HPLC法(反相高效液相法),目的:为测定参苓白术散中的甘草黄酮、人参皂苷含量,进行线性范围的考察和实验方法学研究,同时测定参苓白术散中人参皂苷对羟自由基的抑制情况。结果:人参皂苷Rg1、槲皮素、人参皂苷Re、芦丁分别在0.625~5.000 μg、0.250~1.000 μg、0.375~3.000 μg、0.250~1.000 μg 内对羟自由基的抑制作用显著;芦丁的平均质量分数为0.295 5 mg·g-1;人参皂苷Rg1的平均质量分数为0.193 mg·g-1;槲皮素的平均质量分数为0.243 9 mg·g-1;人参皂苷Re的平均质量分数为0.074 7 mg·g-1。参苓白术散的抗氧化能力经验证也较为明显,人参皂苷对羟自由基的抑制率为79%。

Abstract: The content of ginsenosides and licorice flavonoids in Shenling Baizhu Powder was determined by HPLC, which prepared for the further study of antioxidant activity of Shenling Baizhu Powder in vitro. Objective: to determine the content of liquorice flavonoids and ginsenosides in Shenling Baizhu powder by HPLC (reversed phase high performance liquid chromatography). Methods: the linear range and experimental methods were investigated, and the inhibition of ginsenosides on hydroxyl free radicals was determined. Results: ginsenoside Rg1, quercetin, ginsenoside Re and rutin had significant inhibitory effects on hydroxyl radical in 0.625~5.000 μg, 0.250~1.000 μg, 0.375~3.000 μg and 0.250~1.000 μg, respectively; the average content of rutin was 0.295 mg·g-1; the average content of Ginsenoside Rg1 was 0.193 mg·g-1; the average content of quercetin was 0.2439 The average content of ginsenoside Re was 0.0747 mg·g-1. The antioxidant capacity of Shenling Baizhu Powder was also tested and proved to be more obvious, the inhibition rate of ginseng saponins to hydroxyl free radicals was 79%.

參苓白术散,别名参术饮,具有补益脾胃的作用,可用于治疗食少便溏等症。高效液相法灵敏度高、出峰快,逐渐用于成分复杂的中药成分定性定量中[1],本次实验采用的是反相高效液相法测定参苓白术散中人参皂苷和甘草黄酮含量,并研究其有效成分对羟自由基的抑制效果。
近年来,探究参苓白术散方剂中的抗氧化活性成分一直是参苓白术散研究的热点,而相关研究也证明了参苓白术散方剂中皂苷及黄酮类化合物有较强的抗氧化作用,其含量直接影响了参苓白术散的抗氧化效果。但其含量测定的相关研究较少,HPLC法具有准确性好,灵敏度高的特点,因此我们拟建立一种利用HPLC法同时测定人参皂苷和甘草黄酮含量的方法,为下一步探究参苓白术散的体外抗氧化活性研究做准备。……
