This study to investigate chemical constituents from the aerial of Bupleurum marginatum led to the isolation of a new trierpenoid and a new flavonoid, namely 3β-hydroxy-cycloart-24-en-26-acetyloxy (1), and 3, 3′, 5′-trimethoxyl-myricetin 7-O-β-D–glucopyranoside (2) along with eight known compounds (3–10). Their structures were established by spectral data analyses (MS, 1D and 2D NMR), as well as by comparison of spectral data with those of the related known compounds. The 24-en-lanostane type triterpenoid with a cyclopropane ring (1 and 3) was firstly reported from this specie, which might be chemotaxonomic markers of this specie. In addition, compounds 1 and 2 were examined for their anti-inflammatory activity. Compounds 1 and 2 inhibited the NF κB induction by 60.61% and 24.30%.
