Extraction, characterisation and antioxidant activity of Allium sativum polysaccharide.
Extraction and antioxidant activity of polysaccharide from Allium sativum were investigated. The crude polysaccharide was obtained by the hot water extraction method. The molecular weight of polysaccharide deproteinized with CaCl2 was 7.35x103. It indicated that polysaccharide from Allium sativum consisted of three monosaccharides, namely fructose, glucose, and galactose by HPLC. The polysaccharide had the b glycosidic bond. Moreover, it was proved that the polysaccharide had the potential scavenging ability to superoxide anions and hydroxyl radicals. So, it should be a potential antioxidant.
