- Abstract: OBJECTIVE: To study the terpene constituents from Cunninghamia lanceolata (Lamb.) Hook. METHODS: The ethanol crude extract was fractionalized by using EtOAc, then a series of chromatography methods were used to isolate the terpene compounds and the structures were elucidated by their physicochemical properties and spectroscopic data. RESULTS: Nine terpenes were isolated and identified as 8(17),12E,14-labdatrien-18-al(1),4S,5R,9S,10R-8(17),12,14-labdantrien-18-ol acetate(2),4S,5R,9S,10R-8(17),12,14-labdantrien-18-ol(3),4S,57R,9S,10R-8(17), 12,14-labdantrien-18-oic acid(4),3β-hydroxy-8(17),13E-labdandien-15-oic acid(5), hinokiol(6),8,15-pimaradien-18-oic acid(7),15-nor-14-oxo-8(17),12-labdandien-18-oic acid(8), and 15-nor-14-oxo-8(17),12-labdan-dien-18-ol(9). CONCLUSION: Compounds1,2,5-7 and 9 are isolated from this plant for the first time.
