摘要：

Vacciniin [4] (6-O-benzoyl-D-glucopyranoside) and two new benzenoid glucosides, homaloside A [1] (1''-O-benzyl-3''-O-benzoyl-alpha-L-arabinopyranosyl(1''' --> 4'')-beta-D-glucopyranoside) and homaloside D [2] [1-(1'-hydroxy-6'-oxocyclohex-2'-ene-carboxymethyl)-5-hydroxyphenyl-6''-O-benzoyl-beta-D-glucopymnoside], were isolated from the n-BuOH fraction of Homalium ceylanicum (Flacourtiaceae). A novel cyclohexenone carboxylic acid ester, 1-hydroxy-6-oxocyclohex-2-enoic acid methyl ester [3], was also isolated from this fraction. The structures were elucidated by chemical and nmr (COLOC, FLOCK, and selective INEPT) techniques.
