摘 要:目的:建立磨盘草药材总黄酮的含量测定方法。方法:50%乙醇回流提取1h,以芦丁为对照品,采用紫外-可见分光光度法测定总黄酮含量。结果:本法在60min内测定稳定,芦丁的线性方程:Y=11.323X-0.0139,相关系数r=0.9997(n=6),平均加样回收率为98.47%(n=6),RSD=1.29%。结论:该方法简便、准确、稳定性好,可作为磨盘草药材的质量控制方法。Objective : To establish the quality standard of total flavonoid in Abutilon indicum ( L. ) Sweet. Method : We extracted the total flavonoid by 50 % of ethanol for one hour in water - bath, and used rutin as a reference substance, used UV spectrop hotometer for contentdetermination of flavonoids. Result :The method was stable in 60 minute, the cali- bration curve of rutin at 510nm was Y = 11. 323X -0. 0139, r =0. 9997( n =6), and the average recovery was 98.47% ( n =6) with RSD of 1. 29%. Conclusion : This method was simple accurate and sensitive. It can be used effectively for the quality control of this preparation.
