MANZANO SANTANA, Patricia et al. Chemical study of lipid compounds from leaves, stems and flowers of Vernonanthura patens (Kunth) H. Rob. (Asteraceae). Rev Cubana Plant Med [online]. 2013, vol.18, n.4, pp. 575-585. ISSN 1028-4796.
Introduction: Vernonanthura patens (Kunth) H. Rob. is a species that grows wild in Ecuador. Few chemical and biological studies have been conducted on this species, and none of them deal with lipid fractions. Objectives: study the fractions of lipid compounds present in the leaves, stems and flowers of the species. Methods: the plant was collected in its adult stage, during the flowering season. Plant organs were oven dried separately, ground to 2 mm particle size, and extracted by maceration with ethanol. The concentrated ethanolic extracts were separated by column chromatography. Lipid fractions were separated with hexane, and then saponified and analyzed by coupled gas chromatography mass spectrometry. Results: identification of the fatty acids and unsaponifiable compounds present in the organs studied revealed some differences in their composition. Conclusions: 29 fatty acids and 8 unsaponifiable compounds were identified in the plant organs studied.
