摘　　要：以微波辅助水提醇沉法萃取苦瓜多糖,并用硫酸苯酚定糖法测定所提多糖含量,以正交设计法考察不同料液比、浸提时间和微波功率对苦瓜多糖的提取率的影响.结果确定萃取工艺为:料液比为1∶20;浸提时间为25min;微波功率为600W.利用微波萃取苦瓜多糖是一种新型的提取方式,与传统的浸提法、热回流法等相比有节约时间、提高萃取效率等优势.With the assistance of microwave, using the phenol-sulfuric acid method to determine the content of the polysaccharide in Momordica charantia L,, the extracting conditions were optimized by the orthogonal test. As a result, it showed that the optimum technical parameters were the ratio of [S]/[L] with 1：20, the extracting time with 25 mins under microwave power of 600 W. Compared with the traditional techniques, the assistance of microwave can save extracting time and improve the efficiency.
