Anti-estrogenic activity of (-)-sesamin (1), helioxanthin (2), savinin (3), taiwanin C (4), and 3-(3,4-dimethoxybenzyl)-2-(3,4-methylenedioxybenzyl)butyrolactone (5) isolated from the root of Acanthopanax chiisanensis was tested using Ishikawa cells. Among them, compound 3 exhibited anti-estrogenic
The chloroform and the ethyl acetate fractions from the roots of Acanthopanax chiisanensis exhibited the significant inhibition of TPA-induced prostaglandin E(2) (PGE(2)) production in rat peritoneal macrophages. Five lignans were isolated from the chloroform fraction and their structures were
Five lignans, l-sesamin, savinin, helioxanthin, taiwanin C, and cis-dibenzylbutyrolactone, were isolated from the root of Acanthopanax chiisanensis (Araliaceae), a Korean medicinal plant, and their inhibitory effects on the production of prostaglandin (PG) E(2) stimulated by
The purpose of this investigation is to characterize the inhibition of CYP3A4 by methylenedioxyphenyl lignans isolated from ACANTHOPANAX CHIISANENSIS. Inhibition of CYP3A4 by three methylenedioxyphenyl lignans, avinin, helioxanthin, and
The phytochemical investigation on the roots of Acanthopanax henryi (Araliaceae) resulted in the discovery of twenty compounds whose chemical structures were elucidated by the analysis of 1D-, 2D-NMR, mass spectrometry data, other physicochemical properties, and a comparison of the spectral
