摘 要:建立阳春砂仁中异槲皮苷和槲皮苷含量的高效液相(HPLC)测定方法。异槲皮苷进样量在0.0183~0.0915μg范围内有良好的线性关系,平均回收率为102.69%,相对标准偏差为0.70%(n=6);槲皮苷进样量在0.0294~0.1470μg范围内线性关系良好,平均回收率为103.15%,相对标准偏差为0.68%(n=6)。建立了紫外分光光度法测定砂仁中总黄酮含量的方法,采用槲皮苷为对照品,浓度在0~9.8μg/mL范围内线性关系良好,平均回收率为100.89%,相对标准偏差为1.19%(n=6)。本方法简便快捷,可作为砂仁含量测定质量控制方法。This paper studies the determination of the contents of isoquercitroside and quercitroside in Amomum villosum by using HPLC. A good linear relationship exists between the peak areas and the sample contents within the ranges of 0.018 3-0.091 5 μg and 0.029 4-0.147 μg for isoquercitroside and quercitroside, respectively. The average recovery rates of isoquercitroside and quercitroside are 102.69% (n=6, RSD=0.70%) and 103.15% (n=6, RSD=0.68%), respectively. The UV spectrophotometry is used for determining total flavonoids in Amomum villosum, with quercitroside as the reference, which shows a linear relationship within the range 0-9.8 μg/mL. The average recovery rates of quercitroside are 100.89% (n =6, RSD=1.19%). The methods are simple, rapid and accurate and can be used for quality control of Amomum villosum.
