苦瓜植株各部分黄酮的提取与粗黄酮含量的测定
Study on Extraction and Determining the content of Flavonoids in Momordica charantiaL of Variety Parts
【摘要】 介绍了以苦瓜植株各部分为原料用微波法提取黄酮,通过正交试验对该方法进行了最佳条件的探讨。实验结果表明:以体积分数50%乙醇水溶液作提取溶剂,固液比1∶30(g/mL),微波照射2min,浸提时间1h,提取温度80℃,苦瓜叶中黄酮提取率最高。并用该最佳条件分别提取苦瓜叶、茎、果、根的黄酮类化合物,测其质量分数分别为1.616%、0.453%、1.535%、0.875%。
【Abstract】 The optimum conditions for flavonoids extraction from different party of momorida charantiaL through microwave irradiation were careful investigated.The optimum conditions for flavoids extraction were as follow: the ratio of solid to liquid was 1∶30 with 50% ethanol,microwave time was 2 min,extraction time was 1 h and temperature was 80 ℃.By combinational optimal extraction conditions,a highest flavonids extraction rate 1.616%,0.453%,1.535% and 0.875% was achieved in leaf,stem,fruit and foot,respectively.
