【摘要】 研究點(diǎn)柄粘蓋牛肝菌子實(shí)體多糖的抗氧化活性。結(jié)果顯示,隨著多糖濃度的上升,還原能力不斷增強(qiáng),對(duì).O2-和.OH的清除效果也在加強(qiáng),但多糖濃度更大時(shí),清除率增強(qiáng)效果不明顯,點(diǎn)柄粘蓋牛肝菌子實(shí)體粗多糖對(duì).OH的清除能力較強(qiáng),多糖濃度為0.2 mg.mL-1時(shí)對(duì).OH清除率最大,為98.95%;但對(duì).O2-的清除作用不明顯,多糖濃度為10mg.mL-1時(shí)清除率為21.68%。提取的點(diǎn)柄粘蓋牛肝菌子實(shí)體粗多糖具有抗氧化活性,且活性呈現(xiàn)劑量效應(yīng)。

【Abstract】 The antioxidation activity in vitro of coarse polysaccharide of Suillus granulatus were studied.The results showed that the reduction capacity increased with the increasing concentration of polycaccharide,and also on the ·O2-and ·OH removal effect,but when the polysaccharide concentration was bigger,the effect was not obvious.The ·OH removal effect of the fruit body polysaccharide of Suillus granulatus was better,and when the polysaccharide concentration was 0.2 mg·mL-1,the removal capacity was ...
