Abstract

Three new mexicanolide-type limonoids were isolated together with two known mexicanolides, 2-hydroxyswietenin and swietemahonin G, from the ether extract of the stem bark of Swietenia mahogani JACQ. (Meliaceae). The structure of these compounds was elucidated by spectroscopic means and their biological activities were also tested.
