aiouea/polyprenol

The ethanolic extracts from the roots, the underground trunk and the leaves of Aiouea trinervis were active in the brine shrimp (Artemia salina) lethality assay (LD (50): 1.93, 0.92 and 262.1 microg/mL, respectively). Fractionation of the extracts led to the isolation of four butanolides, namely

Aiouea trinervis Meisn. is a shrub that grows in the "Cerrado" (a savanna ecosystem) of Brazil. In this study, fractionation of ethanol extracts (EEs) from the leaves of A. trinervis led to the isolation of butanolides, namely isoobtusilactone A and obtusilactone A, as well as lignans, namely
