摘要
许多中草药中含有丰富的黄酮类化合物。文章采用分光光度法,以芦丁为标准品,测定四种中草药中总黄酮含量。结果表明,地肤子用80%乙醇提取黄酮效果最好,黄酮的含量最高。平均回收率为104.4%,RSD=4.4%,砂仁,水红花子,紫参等三种样品用60%乙醇提取黄酮效果最好,黄酮的含量最高。平均回收率分别为105.2%,RSD 5=2;103.7%,RSD=3.7%; 98.7%,RSD=1.3%。
Many Chinese herbs have rich flavonoids. Spectrophotometry, as standard, total flavonoid of the four herbs ware contented. The results showed Wancomponents with 80% ethanol extract flavonoids best, the highest content of flavonoids. The average recovery was 104. 4%, RSD=4. 4%. Amomum villosum, Hailian beggar. Zishenxuekan three samples using 60% ethanol extract flavonoids best, the highest content of flavonoids. The average recoveries were 105.2%, RSD=5.2%; 103.7%, RSD=3. 7%; 98. 7%, RSD=1. 3%.
