Abstract

Two new epoxy butenolides, (4S)-4-methyl-2-(9-epoxy-11-dodecynyl)-2-butenolide and (4S)-4-methyl-2-((9Z)-11-epoxy-9-dodecenyl)-2-butenolide were isolated from the dichloromethane extract of Hortonia angustifolia. They were characterized by means of Mass and NMR spectroscopic analysis. The latter compound showed moderate mosquito larvicidal activity against Aedes aegypti.
