Microwave Extracting Process of Total Saponins from Momordica Charantia

The study aimed to research the best extraction process of total saponins from momordica charantia.The absorbance value and total saponins yield as indicators,the effects of microwave power,microwave extraction time,ethanol concentration,ratio of material to liquid on total saponins yield were investigated by single factor and orthogonal design.The optimal conditions were the microwave power 350W,microwave extraction time 10min,ethanol concentration 60%,ratio of material to liquid 1∶ 20.The yield of total saponins from momordica charantia was 0.97%.Compared with traditional extraction methods,The microwave extracting method has the advantages of simple operation,low cost,fast and accurate.
