| 摘 要： | 以红河州民族民间草药青叶胆为试材,用紫外分光光度法对总黄酮含量进行分析,以乙醇和甲醇为提取剂,分别对青叶胆中总黄酮进行提取。结果表明:乙醇和甲醇浓度80%,浸提时间为3d时,总黄酮的提取效果较好,以乙醇作为提取剂的提取效果优于甲醇,总黄酮平均回收率为102.2%,相对标准偏差RSD为1.85%,结果可靠。

| Abstract: | Swertia mileensis herbal medicine of National Folk in Honghe local were used as materials.The total flavonoids in Swertia mileensis were determined by ultraviolet spectrophotometry.The results showed that while alcohol 80% and 80% methanol as extractant,the extracting time was 3 d,the extraction of total flavonoids had good effect.Alcohol had better effect than methanol.The average recovery of this method was 102.2%,the relative standard deviation(RSD)of the method was 1.85 %.Its results were reliable. |
