Abstract

Allium sativum L. is a widely distributed plant used as a spice, vegetable and medicine. In this study, one novel water-soluble polysaccharide (GBP-1a), with a molecular weight of 15.0 kDa, was isolated from the scape of A. sativum (garlic bolt). GBP-1a consists of galactose, glucose and arabinose at a ratio of 73.29:4.36:1.70. It has a backbone, which is composed of 1,4-linked Galp, with 1,2,6-linked Galp branches and 1-linked Glcp residue. In addition, the anti-oxidant activities of GBP-1a, as well as the two main polysaccharide fractions on ABTS radicals, metal ions and superoxide anion radicals, were evaluated in vitro. This study added new data to the study of polysaccharides from garlic bolt.
