| Abstract: | To determine the optimum extraction technology,ultrasonic assisted extraction of polysaccharide from Portulaca oleracea L.were studied,and optimized through single factor test and orthogonal test.The results showed that ultrasonic power 130 W,extraction time 55 min,extraction temperature 75℃,ratio of solvent to raw material 45∶1,and the average extraction yield of polysaccharide was 13.28%.The extraction technology was effective and simpler,and it could provided a reference data for industrial production. |
