Abstract Treatment of convolvulin (the ether insoluble portion of purified jalap resin) with sodium methoxide in methanol has yielded a new β- d -quinovoside. Periodate oxidation and methylation studies together with chemical and spectroscopic analyses have shown this fragment to consist of one molecule of d -quinovose glycosidically linked to a molecule of methyl 11-hydroxytetradecanoate.
