Antioxidants Isolated from Kalopanax pictus
엄나무 유래 신규 항산화 활성물질
Abstract
Screening of new antioxidants form oriental medicines resulted in the isolation of a new antioxidative compound and eight known compounds from the stem bark of Kalopanax pictus. On the basis of various spectrosopic studies, the structure of the new compound was determined to be 4-rhamnose-3,5-dimethoxybenzoic acid methly ester. Other known compounds were identified as ferulic acid, 4,5,6,-trihydroxyflavanone, 2', 4',4' -trihydroxychalcone, caffeic acid, coniferyl alcohol, syringin, 1,3-di-O-caffeoylquinic acid. These compounds showed lipid peroxidation inhibitory acitivity in rat liver microsomes and free radical scavenging acitivity.
