Abstract

Twelve compounds were isolated from the 70% ethanol extract of Lonicera Caulis (Caprifoliaceae) and their structures were identified as six triterpenoids [(24S)-cycloart-25-en-$3{\beta}$,24-diol (1), pomolic acid (7), ursolic acid (8), euscaphic acid (9), hederagenin (10), and 23-hydroxytormentic acid (12)] and six sterols [obtusifoliol (2), gramisterol (3), citrostadienol (4), ${\beta}$-sitosterol (5), ergosterol peroxide (6) and ${\beta}$-sitosterol glucoside (11)]. The chemical structures of these compounds were identified on the basis of spectroscopic methods and comparison with literature values. All the compounds were isolated from this plant parts for the first time.
