从印度黄檀（Dalbergia sissoo Roxb）叶中分离纯化了3种水溶性多糖。（DSLP）、柚木树皮（Tectona grandis L. f（TGBP）和双毛含羞草（Mimosa diplotricha var. diplotricha Sauvalle（MDSP）。采用体外抗氧化和保湿活性试验研究了这三种多糖的抗氧化和保湿活性。研究的抗氧化活性包括超氧化物（O-2（中心点-）），1，1-二苯基-2苦基肼基（DPPH中心点），2，2 '-连氮双（3-乙基苯并噻唑啉-6-磺酸）（ABTS（中心点+）），羟基（OH中心点-），一氧化氮（无中心点），N，N-二甲基-对苯二胺（DMPID中心点+）自由基清除能力、铁离子（Fe 3+）还原能力、亚铁离子（Fe 2+）螯合能力和脂质过氧化能力。该研究表明，在所有抗氧化试验中，TGBP的活性高于DSLP和MDSP。此外，与透明质酸和甘油相比，这三种多糖显示出有效的保湿性能。(C)2013爱思唯尔有限公司保留所有权利。
Three water-soluble polysaccharides were isolated and purified from the leaves of Dalbergia sissoo Roxb. (DSLP), bark of Tectona grandis L. f (TGBP) and seeds of Mimosa diplotricha var. diplotricha Sauvalle (MDSP). Antioxidant and moisture preserving activities of these three polysaccharides were investigated using in vitro methods. The antioxidant activities studied include superoxide (O-2(center dot-)), 1,1-dipheny1-2picrylhydrazyl (DPPH center dot), 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS(center dot+)), hydroxyl (OH center dot-), nitric oxide (NO center dot), N,N-dimethyl-p-phenylenediamine (DMPID center dot+) radical scavenging activities, ferric ion (Fe3+) reducing ability, ferrous ion (Fe2+) chelating and lipid peroxidation activities. The study revealed higher activity of TGBP in all antioxidant assays than DSLP and MDSP. Further, the three polysaccharides showed effective moisture retention properties in comparison with hyaluronic acid and glycerol. (C) 2013 Elsevier Ltd. All rights reserved.
