摘要:

为了建立紫外分光光度法同时测定宽叶独行菜12个不同样点中总黄酮含有量的方法,采用三氯化铝比色法,以芦丁为对照品,在检测波长为421 nm条件下测定宽叶独行菜12个不同样点的总黄酮含量。结果表明,总黄酮在范围内线性关系良好(r=0.998),加样回收率范围为91.83%~102.50%,平均回收率为96.77%,RSD为3.39%。该方法简便准确,重复性好,可为宽叶独行菜的质量控制提供参考。

Abstract:

To establish a method for the simultaneous determination of total flavonoids in 12 different samples of Lepidium latifolium L.by ultraviolet spectrophotometry.AlCl3 colorimetry was used to determine the content of total flavonoids in 12 samples of L. latifolium from different locations with the detection wavelength of 421 nm and rutin as the control.The results showed that the total flavonoids had a good linear relationship (r=0.998).The average recovery of sample addition is 96.77%,which ranged from 91.83%~102.50%,with RSD 3.39%.The method is simple,accurate and reproducible,and can be used as a reference for quality control of L. latifolium.

Key words: total flavonoids, UV spectrophotometry, AlCl3 colorimetry, Lepidium latifolium L.
