Abstract
Three new sesquiterpenoids, 2α-hydroxy-3,3,6α,9β-tetramethyltricyclo[4,3,2(1,4)]undecane (1), 11-acetoxyeudesman-4β-ol (4), and 2α,3β-dihydroxy-4β-methyl-6,8,10-cadinatriene (6), four known sesquiterpenoids (2, 3, 5, and 7), together with eight known diterpenoids (8-15), were isolated from the wood of Cunninghamia konishii. Their structures were determined by detailed analysis of spectroscopic data and comparison with the data of known analogues. Four sesquiterpenoids (1, 4, 5, and 6) and all the diterpenoids (8-15) were evaluated for inhibition of nitric oxide production in lipopolysaccharides (LPS)-activated RAW 264.7 macrophages and the results showed that compounds 10 and 15 exhibited moderate inhibitory activities against nitric oxide production.
