摘　　要：调查 Cinnamomum cebuense 的化学成分的目的，一棵地方性、极其危及的树仅仅在宿务岛发现了，菲律宾。混合物被硅石胶化层析孤立的方法。isolates 的结构被 NMR 光谱学阐明。结果 C 的 bark 的 dichloromethane (DCM ) 摘录。cebuense 负担得起一个新 monoterpene 天赋产品 1 并且新 sesquiterpene 2 与已知的混合物一起， 4-hydroxy-3-methoxycinnamaldehyde (3 ) ， 4-allyl-2-methoxyphenol (4 ) ， -terpineol (5 ) 和 humulene (6 ) 。C 的叶子的 DCM 摘录。cebuense 产出 6， -caryophyllene (7 ) ， squalene (8 ) ，和 -amyrin (9 ) 的混合物， -amyrin (10 ) 和 bauerenol (11 ) 。17 的结构被广泛的 1D 和 2D NMR 光谱学阐明，当 811 的结构被他们有那些的数据在文学报导了的 13C NMR 的比较识别时。结论 C 的 bark。cebuense 负担得起 monoterpenes， sesquiterpenes 和 phenolics，当叶子产出 sesquiterpenes 和 triterpenes 时。AIM： To investigate the chemical constituents of Cinnamomum cebuense, an endemic and critically endangered tree found only in Cebu, Philippines. METHODS： The compounds were isolated by silica gel chromatography. The structures of the isolates were elucidated by NMR spectroscopy. RESULTS： The dichloromethane （DCM） extract of the bark of C. cebuense afforded a new monoterpene natural product 1 and a new sesquiterpene 2, along with the known compounds, 4-hydroxy-3-methoxycinnamaldehyde （3）, 4-allyl-2-methoxyphenol （4）, α-terpineol （5） and humulene （6）. The DCM extract of the leaves of C. cebuense yielded 6, β-caryophyllene （7）, squalene （8）, and a mixture of α-amyrin （9）, β-amyrin （10） and bauerenol （11）. The structures of 1-7 were elucidated by extensive 1D and 2D NMR spectroscopy, while the structures of 8-11 were identified by comparison of their 13 C NMR data with those reported in the literature. CONCLUSION： The bark of C. cebuense afforded monoterpenes, sesquiterpenes and phenolics, while the leaves yielded sesquiterpenes and triterpenes.
