Extraction and antioxidant activity of polysaccharides from the Chinese watermelon was investigated. The polysaccharides were obtained by hot water extraction, ethanol precipitation, and deproteinization with HCl, respectively. The molecular weight was 3.02 × 10. It showed by high performance liquid chromatography (HPLC) and TLC that Chinese watermelon polysaccharides consisted of six monosaccharides, namely glucose, galactose, mannose, xylose, arabinose, and rhamnose. The polysaccharides contained the β-glycosidic bond. Moreover, it was proved that the polysaccharides had high scavenging ability to superoxide anions.
研究了从中国西瓜中提取多糖及其抗氧化活性。多糖分别采用热水提取、乙醇沉淀和盐酸脱蛋白法提取。分子量为 3.02×10。高效液相色谱（HPLC）和薄层色谱（TLC）表明，中国西瓜多糖由葡萄糖、半乳糖、甘露糖、木糖、阿拉伯糖和鼠李糖 6 种单糖组成。多糖含有β-糖苷键。此外，还证明了多糖对超氧阴离子具有很高的清除能力。
