Structure Identification and Antioxidation Activity of A Kind of Phytosterol from Flaxseed

Abstract

Abstract: The compound A was isolated through silica gel column chromatography, its structure was elucidated through physiochemical and spectral analysis, and its activity of monomer was studied by lipid peroxidation of linoleic acid, chemical irritant light reaction. The results showed that the monomer is a new phytosterol, its structure is characterized as 24-ethyl-cholestane- 3-o-β-D-glucopyranoside with strong ability of inhibiting linoleic acid peroxidation, and its capacities of scavenging O2· and ·OH are weak.

Key words: flaxseed, phytosterol, identification, antioxidation
