Preparation and antioxidant activities of polysaccharide from cuaurbit were investigated. The crude polysaccharide was extracted by the hot water method. It indicated that the CaCl method excelled NaCl method in deproteinization. The cuaurbit polysaccharide was linked by the β-glycosidic and α-glycosidic bonds. It consisted of glucose, glucuronic acid, galactose, arabinose, xylose, and rhamnose. Moreover, the antioxidant test showed that cuaurbit polysaccharide had good antioxidant activity and would be a new natural antioxidant with good effect and high safety.
本文研究了冬瓜多糖的制备及其抗氧化活性。采用热水浸提法提取粗多糖，结果表明 CaCl2 法在脱蛋白方面优于 NaCl 法。冬瓜多糖通过β-糖苷键和α-糖苷键连接，由葡萄糖、葡萄糖醛酸、半乳糖、阿拉伯糖、木糖和鼠李糖组成。此外，抗氧化试验表明，冬瓜多糖具有良好的抗氧化活性，将成为一种效果好、安全性高的新型天然抗氧化剂。
