title: A new 3,4-seco-ursane triterpenoid from Glyptopetalum sclerocarpum.
abstract: A new ursane-type triterpene, glyptopetolide, was isolated along with two known triterpenoids, isoarborinol and cangoronine, from the stem bark of Glyptopetalum sclerocarpum LAWS. (Celastraceae). The structure of glyptopetolide was elucidated as 3,4-seco-14alpha,27-cyclo-urs-4(23)-en-3,11alpha-ol ide by spectroscopic analysis.
