Abstract

The methodological condition of extraction polysaccharide from Portulaca oleracea L. under microwave was studied. The influent factors including power of microwave, extracting time, temperature and ratio of solid to liquid were studied. By microwave assisted extraction, the optimum condition of extracting were microwave power 400 W, ratio of solid to liquid 1:10 , 70℃ for 4 min. The extract ratio was 10.8%.
