				        	Five undescribed sesquiterpenoids (1-5), and nine known sesquiterpenoids (6-14) were obtained from the fruits of Litsea lancilimba Merr. by LC-MS/MS molecular networking strategies. Litsemene A (1) possessed a unique 8-member ring through unexpected cyclization of the methyl group on C-10 of guaiane. Their structures were elucidated by spectroscopic techniques including IR, UV, NMR, HR-ESI-MS, and their absolute configurations were assigned by ECD calculations. All isolated sesquiterpenoids were analyzed by bioinformatics and evaluated for their neuroprotective effects against H2O2-induced injury in human neuroblastoma SH-SY5Y cells.
