摘要
试验采用石油醚脱脂后,用紫外分光光度法对马蹄香中的总黄铜含量进行分析。结果表明:采用提取时间12h,提取剂乙醇浓度为50%和60%时,总黄铜的提取效果较好,平均回收率为102.1%,回收率好。
In this test,degreasing with petroleum ether,the total flavonoids in Valeriana jatamansi were determined by ultraviolet spectrophotometry.The results showed that while the extracting time was 12 h,alcohol 50%and 60%as extractant,the extraction effect of total flavonoids was relatively high.The average recovery of this method was 102.1%,the recovery was good.
