Y. Shirataki et al., ANTIOXIDATIVE COMPONENTS ISOLATED FROM THE ROOTS OF ASTRAGALUS-MEMBRANACEUS BUNGE (ASTRAGALI-RADIX), PTR. Phytotherapy research, 11(8), 1997, pp. 603-605
Antioxidative components in the methanol extract of the root of Astrag
alus membranaceus Bunge were investigated by using an evaluation metho
d based on the air oxidation of linoleic acid. Afrormosin, calycosin a
nd odoratin were found to be active components, These antioxidative ac
tivities are superior or similar to those of butyl hydroxytoluene and
alpha-tocopherol. (C) 1997 John Wiley & Sons, Ltd.
