title: Triterpenoids from aerial parts of Glochidion eriocarpum.
abstract: From the aerial parts of Glochidion eriocarpum, a new triterpene, glochieriol (1), three new triterpenoid saponins, glochieriosides C - E (2 - 4), together with four known triterpenes (glochidonol, glochidiol, lupeol, and 3-epi-lupeol) were isolated by using combined chromatographic separations. The structures of the new compounds were elucidated on the basis of spectroscopic data, including FTICR-MS, 1D and 2D NMR.
