摘要

目的:对广西产赪桐根中总黄酮的提取工艺进行研究

建立其含量测定方法。方法:以总黄酮含量为考查指标

采用正交试验优选提取工艺;以芦丁为对照品

采用紫外-可见分光光度法测定

测定波长506 nm。结果:总黄酮的线性范围为8.584～51.504 mg.L-1（r=0.999 4）

平均加样回收率为100.11%

RSD 0.24%（n=6）;最佳提取工艺为15倍量50%乙醇超声提取1.5 h。结论:建立了赪桐根中总黄酮最佳的提取工艺和含量测定的方法

所建立的体系精确可靠。

Abstract

Objective:To optimize extraction technology of total flavones from the roots of Clerodendrum japonicum in Guangxi and establish its content determination method.Method:Orthogonal experiments were used to optimize extraction technology.Rutin was defined as the standard and UV method was adopted.The detective wavelength was at 506 nm.Result:The linearity was in the range of 8.584-51.504 mg·L-1（r=0.999 4）.The average recovery rate was 100.11% with RSD of 0.24%.Optimum conditions of ultrasonics extraction were as follow:extracted with 15 times the amount of 50% ethanol in 1.5 hour.Conclusion:High effciency extraction method and accurate and reproducable content determination method of total flavones from the roots of C.japonicum has been estabished

which paved the way for further exploitation.
