中文摘要：

以银叶树果壳为试材,采用单因素试验和响应面法研究了水浴醇提银叶树果壳多糖的工艺条件,并考察其对DPPH·、·OH的清除能力。结果表明：银叶树果壳多糖的最佳提取工艺为,提取温度72℃、提取时间53min、液料比64∶1mL·g^-1、提取次数2次,该条件下银叶树果壳多糖得率为14.01%。银叶树果壳多糖对DPPH·、·OH均具有一定的清除能力,其清除能力与多糖浓度呈线性关系,表明银叶树果壳多糖具有较好的抗氧化能力。

英文摘要：

Heritiera littoralis shell was used as materials,the process conditions of using alcohol water bath method to extract Heritiera littoralis shell polysaccharide was studied by single factor test and response surface analysis,as well as the scavenging effect of Heritiera littoralis shell polysaccharide on DPPH· and hydroxyl radical were studied.The results showed the optimal extracting conditions were as follows,extracting temperature 72 ℃,extracting time 53 minutes,liquid-solid ratio 64∶1mL·g^-1,extracting twice.Under such conditions,the extraction ratio of Heritiera littoralis shell polysaccharide was 14.01%.Scavenging effect of Heritiera littoralis shell polysaccharide on DPPH· and hydroxyl radical were obvious,which appeared linear.It showed that the antioxidation activity of Heritiera littoralis shell polysaccharide appeared well.
