Three new sesquiterpenes, 4S-1-(3-hydroxybutyl)-7-(11-hydroxypropyl)-10-methyl- cyclohepta-7,5,10-trien-8-one (1), 8R-hydroxy-7-(4S-4,10-dimethyl-5-oxooct-1-en-7-yl)-11- methylfuran-12-one (2), (1S,5R,7S,10R)-1-hydroxy-7-(11-hydroxypropyl)-10-methyl-4- methyleneoctahydronaphthalen-8-one (3), along with 30 known terpenoids (4-33) were obtained from the rhizomes of Curcuma kwangsiensis S.G. Lee et C.F. Ling. Through comprehensive analysis of chemical evidence and spectral data including UV, ECD, IR, 1D and 2D NMR and HR-ESI-MS, as well as quantum chemical calculation, the structures of these novel compounds were successfully determined. Additionally, the inhibitory effects of compounds 1-2, 4-33 on NO production were evaluated in lipopolysaccharide (LPS)-induced RAW264.7 cells. Notably, compound 33 exhibited the most significant inhibitory effect with an IC 50 value of 3.55 ± 0.55 μM.
