摘要

Chrysosplenium carnosum, an original plant used in traditional Tibetan medicine known as “Yajima”, was subjected to phytochemical study. This led to the isolation of a new hexanor-cucurbitane triterpenoid, namely chrycarnin A (1), along with three previously known structurally related analogs (2–4). Their structures were determined by spectroscopic methods, including 1D and 2D NMR, UV, IR, ECD, and HR-ESI-MS, and comparison of the spectroscopic data with those reported in the literature.
