Dracontium spruceanum (Schott) G.Zhu ex Dracontium loretense Krause is a plant native to Central America and the Amazon region of the South American continent. This plant receives different names such as Jergón sacha, Ronon rao (Shipibo-conibo), Hierba del jergón, Shano yora, Du un yubi (Cashinahua), Jararaca, Hierba de santa maría, Taja de cobra, Fer de lance, as well as, it is attributed various uses in traditional medicine for treatment and prevention of conditions. This plant stands out for its traditional use to counteract the venom of the Bothrops atrox. Phytochemical studies preceding this work demonstrate the variability of secondary metabolites present in túbero plant (corms, rhizome), as well as the presence of steroids from aglycones, glycosylated and acylglycosylated, p-hydroxybenzaldehyde, p- hydroxybenzoic, sugar, oxilipins, ceramides and cerebrosides. So far, identification of flavonoids has not been reported. The present work was carried out in the ethyl acetate residue obtained by liquid-liquid partition of the ethanolic extract of the species studied. The phytochemical study of the ethyl acetate residue was carried out by analytical liquid chromatography and semi- preparative liquid chromatography for isolation of 3’-methylcercetinyl-3-0-a-L- rhamnopyranosyl-(16)-β-D-glucopyranoside. Its identificationwas through the analysis of its hydrogen nuclear magnetic resonance, carbon 13 and mass spectra. This flavonoid was reported for the first time in D. spruceanum, but it has already been reported in Lasia spinose, other species belonging to the family of the Araceae.
