【摘要】 姜樟鲜叶经水蒸汽蒸馏得到一种淡黄色的精油,得率为0.5-0.8％。我们应用气相色谱、红外光谱、气相色谱/质谱/计算机联用以及测定衍生物熔点等方法,对该精油进行成份分析、鉴定。共鉴定出α-,β-柠檬醛,香叶醇,柠檬烯,1,8-桉叶油素,芳樟醇,氧化芳樟醇,樟脑,龙脑,石竹烯等47个已知化合物,其中α-,β-柠檬醛含量高达64.11％。它们是香料工业和医药工业上的重要原料。更多还原

【Abstract】 Jiang-Zhang is a Physiological type of Cinnamomum porrectum(Roxb.) Kosterm.The essential oil of leaves of Jiang-Zhang can be extracted by steam distillation with yields of 0.5—0.8%.It contained citral(α-,β-citral)64.11% and can be used in aromatic and medicinal industries,We used the methods of GC,IR,GC/MS/DS and prepared deriva- tive and 47 chemical constituents were identified as follows:α-thujene(0.06%),α-pinene (2.42 %),camphene(1.26 %),sabinene (0.21%),β-pinene(1.38 %),myrcene(0.38 %), α-phellandrene(0.32 %),△~3-carene(0.01%),p-cymene(0.21%),α-limonene(1.57 %),1, 8-cineole(0.82%),β-phellandrene(0.10%),cis-linalool oxide(0.07%),linalool(8.43%) epicamphor(0.26 %),camphor(1.10 %),borneol(1.07%),β-citral(neral)(28.28 %),geraniol (0.25%),nerol(0.47%),α-citral(geranial)(35.83%),methyl citronellate(0.12%), n-undecane(0.18),safrole(0.02),methyl geranate(0.23%),geranyl formate(0.09%), α-copaene(0.12%),trans-methyl cinnamate(0.02%),n-dodecane(0.20),β-elemene (0.12%),caryophyllene(4.67%),α-guaiene(0.04),β-guaiene(0.06%),β-selinene (0.97%),azulene(0.38%),β-cubebene(0.30 %),n-pentadecane(0.05%),β-gurjunene (0.04%),epi-β-santalene(0.46 %),aremophilene(0.05 %),alloaromadendrene(0.03%), α-elemene(0.26%),trans-β-farnesene(0.04%),(z)-β-farnesene(0.30%),r-elemene (0.03%),β-bisaboiol(0.41%),cedrol(0.16%),respectively.更多还原
