RESUMEN
Column chromatography on silica gel and Sephadex LH-20 was used to study the chemical constituents of Homalomena occulta. The chemical structures of the separated compounds were elucidated by spectroscopic data analyseS. Twelve compounds were obtained and identified as 5-pentylresorcinol-b-glucoside (1), protocatechuic acid (2), 4-hydroxybenzoic acid (3), vanillic acid (4), 5-hydroxymethyl-2-furancarboxylic acid (5), 2-furoic acid (6), 5-hydroxymethyl-2-furfural (7), (R) -malic acid (8), (R) -dimethyl malate (9), trimethyl 1,2,3-propanetricarboxylate (10), 4-hydroxytetrahydrofuran-2-one (11) and (1S, 2S, 4S)-p-menthane-1,2, 4-triol (12). Among them, compound 1 was a new natural product, and compounds 4-12 were isolated from the genus for the first time.
