摘要:

选取甘草提取液中典型有效成分甘草苷和甘草酸,建立其高效液相色谱检测方法。样品用质量分数为50%乙醇提取,以Agilent ZORBAX SB-C18 (4.6 mm×250 mm×5 μm)为分析柱,乙腈-0.05%磷酸梯度洗脱,流速1.0 mL/min,检测波长237 nm。结果表明,该方法测试时间短,测试结果准确;在0.5~100 μg/mL范围内线性良好,相关系数均大于0.999 5; 空白样品中加标回收率为91.47%~114.57%,相对标准偏差为0.87%~3.32%。该方法准确、可靠,适用于化妆品原料甘草提取液中甘草苷和甘草酸的测定。

Abstract:

A comprehensive analytical method based on high performance liquid chromatography (HPLC) was developed for the determination of liquiritin and glycyrrhizic acid in licorice extract in cosmetics. The target compounds were extracted with 50% ethanol, separated on a Agilent ZORBAX SB-C18 column (4.6 mm×250 mm×5 μm) in gradient elution program using acetonitrile and 0.05% phosphoric acid as mobile phases, at flow rate of 1 mL/min, and detection wavelength of 237 nm. The method had a short test time and accurate test results, it showed good linear relationship between 0.5-100 μg/mL with correlation coefficients larger than 0.999 5. The spiked recoveries in the blank sample were in the range of 91.47%-114.57% with the relative standard deviations of 0.87%-3.32%. The results indicate that the developed method is rapid, accurate and reliable, which is suitable for the determination of liquiritin and glycyrrhizic acid in licorice extract in cosmetics.
