Terpenos isolados de Coussarea platyphylla Müll. Arg. (Rubiaceae)

The phytochemical investigation of Coussarea platyphylla led to the isolation of triterpenes betulonic and betulinic acid, monoterpenes monotropein and monotropein salt, the diterpene trans-phytol and esteroids. The structures of the isolated compounds were assigned on the basis of spectroscopic data, including two-dimensional NMR methods. The antiproliferative properties against human cancer cell lines and molluscicidal activity against Biomphalaria glabrata of the crude methanolic extract and of its fractions were investigated.
