番荔枝种子粗多糖抗氧化能力研究
Antioxidant Ability of Crude Polysaccharides from Sugar Apple (Annona squamosa L.) Seeds
摘要
Abstract
In order to explore the antioxidant ability of the polysaccharides of sugar apple seeds, different concentrations of solutions were made with the crude extracts by crushing and homogenating dry seeds, ethanol refluxing, reduced pressure concentration, chloroform extraction and methanol petroleum ether extraction. With the same concentration of vitamin C as the control, the reduction ability, the resistance to peroxidation, and the ability to remove DPPH ? Radicals, superoxide radical (O2-) and hydroxyl radicals (·OH) of polysaccharides from sugar apple seeds were determined. The results showed that the polysaccharides exhibited a strong reduction ability, a good inhibitory effect to lipid peroxidation, and a strong ability to remove DPPH· free radicals, superoxide radical (O2-) and hydroxyl radicals (-OH), and suggested that the polysaccharides of sugar apple seeds had a strong antioxidant ability, and the oxidation resistance was stronger with the increase of concentration. But its antioxidant ability was weaker than vitamin C.关键词
