phytochemical study of methanol extracts from Vernonanthura patens’s leaves located in Marcabelí (El Oro province), Ecuador. The methodology
consisted of chromatographic column separations with increasing polarity
solvents and the analysis of fractions by Gas Chromatography-Mass Spectrometry
coupled system (GC-MS). The structure of 53 compounds was proposed. Analyzed V. patens species showed the presence of
terpene and aliphatic hydrocarbons, free fatty acids and their methyl and ethyl
esters, oxygen sesqui,
triterpenoids and sugars. For ecuadorian species, there are no records of chemical studies.
