Chloranthus fortunei (family Chloranthaceae), a perennial herb, widely distributed in south China with an altitude of 170-340 m. The whole plants were used as an anti-inflammatory agent for the treatment of cough, arthritis and tumor. Five previously unreported compounds fortulactones A-E were isolated from the aerial part of Chloranthus fortunei. Their structures were elucidated using 1D/2D NMR and HRESIMS and their absolute configuration were determined using the ECD excitron chirality method. All isolates were tested for inhibitory effects on the NO production of liposaccharide (LPS)-induced RAW 264.7 macropahges. The most potent compound 1 was further evaluated its protective activity against LPS stimulated A549 cells, the ELISA kits results showed the abnormal states of MDA and SOD were corrected to a certain extent. Meanwhile, the proinflammatory cytokine, such as TNF-alpha, IL-6 and IL-1 beta were also attenuated. In conclusion, these results showed that 1 exhibited therapeutic potential for ameliorating ALI.
