摘　　要：[目的]优化鸡眼草中黄酮类化合物的提取条件。[方法]以鸡眼草的总黄酮提取率为评价指标,通过单因素试验对微波辅助提取鸡眼草黄酮类化合物的工艺条件进行了研究,再运用正交分析法确定最佳提取条件。[结果]微波辅助提取鸡眼草中的黄酮类物质的最佳条件为:乙醇浓度为50%、料液比1∶30(W/V,g/ml,下同)、微波功率300 W,微波处理时间25 min;在此条件下,鸡眼草的总黄酮提取率为3.28%。[结论]微波辅助提取鸡眼草中的黄酮类物质,操作简单易行,提取率较高,是一种理想的提取方法。[-Objectivei To study the optimal conditions for extracting total flavonoids from Kummerowia striata （Thunb）＇Schindl.. [Meth- od] The technological conditions of microwave-assisted extraction of flavoniods were investigated by the single factor and orthogonal experi- ments, and were assessed according to the extraction rate of tatol flavonoids. [ Result] The optimum conditions of microwave-assisted extrac- tion were 50% ethanol as solvent, 1：30 （ W/V, g/ml） of solid-liquid ratio, 300 W of microwave power and 25 min of microwave extraction time. Under the conditions, the extraction rate of total falconoid was 3.28%. [ Conclusion] The microwave-assisted extraction extracting fla- voniods in Kummerowia striata （Thunb.） Schindl. is a simple and ideal extraction method with high efficiency.
