title: Purification, antioxidant and hepatoprotective activities of polysaccharide from Cissus pteroclada Hayata.
abstract: Polysaccharide of Cissus pteroclada Hayata (CPHP) was extracted and purified. Three major fractions (CPHP I, CPHP II-1 and CPHP II-2) from the CPHP were purified by column chromatography and investigated for their monosaccharide compositions, scavenging radical effects and hepatoprotective activities in vitro. The results showed that glucose and galactose were the main monosaccharides of three polysaccharide fractions, CPHP II-1 and CPHP II-2 were acidic polysaccharide fractions which contained glucuronic acid and galacturonic acid. Antioxidant activity determination suggested that CPHP I and CPHP II-1 had a higher scavenging effects on DPPH, superoxide radical, hydroxyl radical and ABTS radical. And the results of antioxidant test in vitro showed that CPHP II-2 could significantly increase (P<0.01) the activities of SOD and GSH-Px and decreased MDA level in human hepatocyte cell line (HL7702 cell), which indicating that CPHP II-2 possessed good hepatoprotective activity.
