Inga marginata Willd., popularly known as ingá-feijão, is a native plant from Mata Atlântica (Atlantic Forest) found in all national territory. It is used for reforestation of riparian buffers, because of this plant's adaptive capacity in humid environment and waterlogged soil, and for urban reforestation. This work proposed the identification of the components present in the ethanolic extract from Inga marginata Willd. seedling's leaves through analytical technics such as liquid chromatography, mass spectroscopy, one and two-dimensional magnetic resonance, ultraviolet and infrared as well as comparing with the literature, which permitted clarify four flavonoids from the flavonols class: myricetin-3-O-α-L-rhamnopyranoside (C5), myricetin-3-O-(2'-O-galloyl)-α-L-rhamnopyranoside (C10), quercetin-3-O-α-L-rhamnopyranoside (C9) and myricetin 4'-methylether-3-O-rhamnoside (C8). This is the first report in the C8 genus, since the C9 and C10 substances were firstly identified in Inga marginata seedling's leaves while the substance C5 had already been reported in leaves from the adult plant.
