Chromatographic separation of the ethyl acetate extract of the aerial parts yielded a new antimalarial α-pyrone, lippialactone (2). Lippialactone is active against the chloroquinesensitive D10 strain of Plasmodium falciparum with an IC50 value of 9.1 μg/mL, and is also mildly cytotoxic. The relative stereochemistry of lippialactone was determined by molecular modeling based on the determination of the relative configuration by quantum mechanical GIAO 13C chemical shift calculations.en© 2013 Elsevier B.V.
