Antimalarial Principles from Artemisia indica

Activity-guided investigation of Artemisia indica Willd. has led to isolation of exiguaflavone A, exiguaflavone B, maackiain, and 2-(2, 4-dihydroxyphenyl)-5,6-methylenedioxybenzofuran. Exiguaflavones A and B exhibit in vitro antimalarial activities of 4.60 x 10(-6) and 7.05 x 10(-6) g/mL, respectively, against Plasmodium falciparum.
