Three new lupane-type triterpenoids (1-3), three new oleane-type triterpenoids (4-6), as well as two known compounds (7-8) were isolated from Euonymus carnosus. The structures of the compounds were elucidated on the basis of spectroscopic data analyses, including UV, IR, MS, and NMR experiments. The inhibitory on LPS-induced NO production in microglia BV2 cells of compounds 1-8 were also evaluated. Compounds 1 and 2 showed moderate abilities to inhibit NO production, with IC values of 5.99 and 8.47μM, respectively.
