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.
从硬荚沟瓣（卫矛科）的茎皮中分离出一种新的乌苏烷型三萜化合物——沟瓣醇内酯，以及两种已知的三萜类化合物——异乔木醇和苍耳酮。通过光谱分析确定了沟瓣醇内酯的结构为3,4-裂环-14α,27-环-乌苏-4(23)-烯-3,11α-内酯。
