Abstract

A new compound 3-acetyloxy-epicycloeucalenol-24-one (1), with 11 known compounds 3α-acetyloxy-4α,14α-dimethyl-9β,19-cycloergost-24-oic acid (2), 3-epicycloeucalenol (3), 3-epicycloeucalenyl-24-one (4), 3-epicycloeucalenyl acetate (5), 4β,14α-dimethyl-5α-ergosta-9β,19-cyclo-24(31)-en-3β-hydroxy-4α-carboxylic acid (6), cycloeucalenone (7), friedelin (8), epifriedelanol (9), lup-20 (29)-en-3β,30-diol (10), betulin (11), lupeol (12), was isolated from the stems and leaves of Quercus variabilis Blume. Seven compounds (1-7) showed anti-inflammatory activity.
