摘要：
Novel small-molecule polysaccharide fractions, named POP II and POP III, were purified from Portulaca oleracea L. with average Mw values of 9.25 and 8.03 kDa, respectively. Monosaccharide analysis revealed that POP II was composed of Rha, Ara, Man, Glc, and Gal with molar ratios of 1: 1.42: 0.44: 0.88: 1.59. POP III was composed of Rha, Ara, Glc, and Gal with molar ratios of 1: 1.16: 0.23: 0.59. The antioxidant activities of the fractions were evaluated using cell-free and cell-mediated radical generating systems. POPII and POP III possessed strong antioxidant activities in both systems. The 2 novel polysaccharide fractions extracted from P. oleracea L. can be developed as natural antioxidants for treatment of free radical-related diseases.
