Abstract

Leaves and flowers of Artemisia gorgonum (Asteraceae) collected in Fogo, Cape Verde islands, were phytochemically investigated and resulted in isolation and characterization of three guaianolides 1, 2, 5, and a secoguainolide 4, in addition to eight known guaianolides 6-11 and two known germacranolides 12, 13. Structures were elucidated by 1D and 2D NMR experiments. Careful examination of the ¹³C NMR spectrum led to revision of the structure of a previously described guaianolide from 2 to 3. Most compounds exhibited mild antiplasmodial activities, ridentin (13) being the most interesting with an IC₅₀ of 3.8 ± 0.7 μg ml^-1 against Plasmodium falciparum FcB1 and weak cytotoxicity in a vero cell line (IC₅₀ 71.0 ± 3.9 μg ml^-1).
