OSORIO, Nicolás; CHARRY, Paula A.; RIOS-VASQUEZ, Eunice  and  CASTANEDA-GOMEZ, Jhon F.. Organic Acids of Resin Glycosides from Three Ipomoea Species (Convolvulaceae). Rev. ion [online]. 2018, vol.31, n.1, pp.55-58. ISSN 0120-100X.  http://dx.doi.org/10.18273/revion.v31n1-2018009.

Esterifying residues from resin glycosides from three Ipomoea species (Ipomoea trífida, Ipomoea purpurea and Ipomoea hederifolia) were identified by gas chromatography and mass spectrometry (CG-MS).These species are invasive of coffee plants and were collected in Quindío, Colombia. First, the extracts with resin glycosides were degraded through saponification to liberate of organic acids soluble in ether and Chloroform. Decanoic, dodecanoic and hexadecanoic acids were the most common esterifying residues from the studied species.

Keywords : convolvulaceae; Ipomoea; organic acids; resin glycosides; gas chromatography.
