Abstract: Phytochemical investigation of the flowers of Wedelia paludosa afforded two diterpenes, ent-kaur-16-en-19-oic acid and ent-kaur-9(11),16-dien-19-oic acid, three acylated triterpenes, 3beta-O-hexa-decanoylolean-12-en-28-oic acid, 3beta-O-pentadecanoylolean-12-en-28-oic acid and 3beta-O-tetradecanoylolean-12-en-28-oic acid, and three steroids, stigmasterol, 3beta-O-beta-D-glycopyranosyl sitosterol and 3beta-O-beta-D-glycopyrano-sylstigmasterol. The substances were identified by their spectral data.
