摘要

目的:建立测定青蒿中青蒿素含量的紫外分光光度检测方法

为筛选收购优质青蒿提供快速检测的方法。方法:用紫外分光光度计对青蒿素标准溶液进行波长扫描

确定最适吸收波长

在最适吸收波长下建立青蒿素标准品的吸光度-浓度曲线。根据标准曲线测定青蒿样品中青蒿素的含量。结果:青蒿素的最适吸收波长为290.5nm

吸光度-浓度回归方程为:Y=0.043X+0.006

不同青蒿样品中青蒿素含量有差异。结论:紫外分光光度法测定青蒿中青蒿素成分含量操作简便、快捷、准确。

Abstract

Objective:Establishing a simple useful method of the ultraviolet spectrophotometric to determine the arteannuin element content

providing the fast basis for screening and shopping high quality arteannuin.Method:Carrying on the wave length scanning with the ultraviolet spectrophotometer to arteannuin element standard solution

establishing the standard curve

according to standard curve determination sample content. Results:Arteannuin element most suitable absorption wave length is 290 nm

and the extinction-density regression equation is:Y=0.043X+0.006. The different arteannuin element sample content has the difference.Conclusion:The method of ultraviolet spectrophotometric determining arteannuin element content operation is quickly

simple and accurate.
