摘要

Phytochemical investigation on Chrysosplenium carnosum Hook. f. & Thomson, the source plant of Tibetan medicine “Yajima,” resulted in the isolation and characterization of a new hexanor-cucurbitane triterpenoid, namely 3-epi-hexanorcucurbitacin F (1), along with 20 known compounds (2–21). Their structures were determined by comprehensive spectroscopic analysis, including 1D and 2D NMR, UV, IR, and HR-ESI-MS, and comparison of the spectroscopic data with those reported in the literature.
