✦ Synopsis

Antioxidative components in the methanol extract of the root of Astragalus membranaceus Bunge were investigated by using an evaluation method based on the air oxidation of linoleic acid. Afrormosin, calycosin and odoratin were found to be active components. These antioxidative activities are superior or similar to those of butyl hydroxytoluene and ␣-tocopherol.

Possible inhibitory effects were investigated of isoflavones in the roots of Astragalus membranaceus BUNGE (Astragali Radix), afrormosin, calycosin, formononetin and odoratin on lipid peroxidation by reactive oxygen species. Calycosin inhibited lecithin peroxidation which was induced by hydroxy radi
