title: Antiplasmodial agents from the leaves of Glossocalyx brevipes.
abstract: A phytochemical study of the methylene chloride/methanol (1/1) extract of the leaves of Glossocalyx brevipes Benth. (Monimiaceae) afforded three new derivatives of homogentisic acid, methyl 2-(1'beta-geranyl-5'beta-hydroxy-2'-oxocyclohex-3'-enyl)acetate (1), 2-(1'beta-geranyl-5'beta-hydroxy-2'-oxocyclohex-3'-enyl)acetic acid (2), methyl 2-(1'beta-geranyl-5'beta-hydroxy-4'beta-methoxy-2'-oxocyclohexyl)acetate (3), and two known alkaloids, aristololactam BII and liriodenine. Compounds 1 and 2 and liriodenine showed modest in vitro activity against Plasmodium falciparum.
