Abstract
A new triterpenoid, named nigrumol A (1), along with 5 known triterpenoids were isolated from the aerial parts of Empetrum nigrum subsp. asiaticum (Nakai ex H.Ito) Kuvaev (E. nigrum) . The structure of 1 was elucidated by analysis of its spectroscopic data, including UV, IR, HR-ESI-MS and extensive 1 D and 2 D NMR techniques. Compound 1 showed that it could decrease ethanol-induced or CCl4-induced L02 cell toxicity effectively.
