抗病毒草药金银花的化学成分分析(二)——金银花中总黄酮的光谱分析

Analysis of chemistry constituents of Lonicera Similis Hemsl on anti-virus chinese traditional medicine (Ⅱ):determination of total flavonoids in Lonicera Similis Hemsl

采用加热回流法和超声波法从金银花中提取黄酮类化合物 ,并建立了金银花中总黄酮的光谱分析方法 .本法的回收率为 98.0 %～ 1 0 3.0 % ,变异系数小于 0 .6 2 % .方法的准确度与精密度均令人满意 。

The heating reflux and ultrasonic methods were employed in extracting flavonoidsof Lonicera Similis Hemsl and the flavonoidswere determined by specyrometric method. The results show that ultrasonic method is more advantageous than heating reflux methods,therecovery is 98.0%～103.0 % and the coefficient of variation is 0.62 %.
