CARVALHO, Geizi Jane A. de et al. Diterpenes, triterpenes and steroids from flowers of Wedelia paludosa. Quím. Nova [online]. 2001, vol.24, n.1, pp.24-26. ISSN 0100-4042.

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, 3b-O-hexa-decanoylolean-12-en-28-oic acid, 3b-O-pentadecanoylolean-12-en-28-oic acid and 3b-O-tetradecanoylolean-12-en-28-oic acid, and three steroids, stigmasterol, 3b-O-b-D-glycopyranosyl sitosterol and 3b-O-b-D-glycopyrano-sylstigmasterol. The substances were identified by their spectral data.

Keywords : Wedelia paludosa; kaurenoic acids; b-O-acyloleanoic acids.
