Li, Yaping published the artcileCharacterization of a polysaccharide with antioxidant and anti-cervical cancer potentials from the corn silk cultivated in Jilin province, Quality Control of 59-23-4, the main research area is corn silk polysaccharide anticervical cancer antioxidant activity; Anti-cervical cancer; Antioxidant; Characterization; Corn silk; Polysaccharides.
Corn silk polysaccharides (CSPs) were extracted from the corn silk cultivated in Jilin province, China, where is one of the golden corn belts worldwide. Three fractions (CSP-1, CSP-2 and CSP-3) were obtained by DEAE-52 cellulose and the former two fractions were further purified by Sephadex G-150 column chromatog. to obtain CSP-S-1 and CSP-S-2. The mol. weights of CSP-S-1 and CSP-S-2 were calculated to be 586 kDa and 813 kDa, resp. CSP-S-1 was composed of galactose, arabinose, xylose and rhamnose at a molar ratio of 4.16:1.00:1.01:6.32 and CSP-S-2 was composed of galactose, arabinose, glucose and rhamnose at a molar ratio of 8.71:3.58:0.169:1.00. CSP-S-2 outperformed CSP-S-1 in scavenging DPPH, ABTS and hydroxyl radicals, and significantly inhibited the proliferation of HeLa cells. IR and NMR anal. indicated that CSP-S-2 was pyranose. CSP-S-2 consisted of 1 → 4 and 1 → 6 linkages and exhibited a triple helix configuration. In summary, CSP-S-2 possesses high potential to be developed as a novel antioxidant and anti-cervical cancer agent.
