The new 5-methyl-4-hydroxy-3(2H)-furanone glucoside (psydrin) and the new 5-O-E-caffeoyl-b-D-apio-D-furanosyl-(1→6)b-D-glucopyranosyl (benzoic acid ester (psydroside) were isolated from the leaves of Psydrax livida. The new 2-(2-hydroxy)-ethanol-β-d-glucopyranoside was found in the leaves of Oxyanthus speciosus subsp. gerrardii and geniposidic acid in the leaves of Canthium gilfillanii. All species belong to the Rubiaceae.

Rubiaceae, phenylpropanoid glycosides, furanone glucoside, Psydrax livida, Oxyanthus speciosus, Canthium gilfillanii, psydroside, psydrin, geniposidic acid
