Artemisterol, a new steryl ester from the whole plant of Artemisia apiacea

Abstract

A new steryl ester, artemisterol (1), together with known compounds α-amyrin (2), β-amyrin (3), β-sitosterol (4), 5,6,7-trimethoxycoumarin (5), and 6-methoxy-7,8-methylenedioxycoumarin (6), were isolated from the methanolic extracts of Artemisia apiacea by repeated column chromatography. The structure of 1 was elucidated as stigmast-5-en-3β,29-diol 29-p-hydroxycinnamate by spectral data analyses.
