Treatment of the ether-insoluble resin glycoside (convolvulin) fraction from seedsof Quamoclit pennata (Convolvulaceae) with indium(III) chloride in methanol provided three oligoglycosides of hydroxy fatty acid (glycosidic acid) methyl esters and two methyl glycosides, which were partially acylated by a glycosidic acid, 75-hydroxydecanoic acid 7-0-β-d-quinovopyranoside (quamoclinic acid B) and/or two organic acids, (E)-2-methylbut-2-enoic (tiglic) acid and/or 3R-hydroxy-2R-methylbutyric (nilic) acid. Theirstructures were elucidated on the basis of spectroscopic data and chemical conversions.
