水蒸汽蒸馏巴柑檬叶和果皮精油化学成分的研究   总被引:1,自引:0,他引:1  
巴柑檬是我们第一次从国外引种成功的一种名贵香料植物。用色谱-质谱-计算机联用技术、毛细管气相色谱保留指数法和标准品叠加法分析了水蒸汽蒸馏巴柑檬叶和果皮精油的化学成分。从叶和果皮精油分离出来的220个和200个成分中,分别鉴定出48个和57个成分。鉴定组分的含量分别占叶和果皮精油的99.80%和98.54%。叶精油与果皮精油在化学成分方面的主要区别是叶油中萜烃化合物含量较低,而萜醇类化合物含量较高。  相似文献

Citrus bergamia Risso. is a rare perfumery plant. Taxonomists have different viewson the taxonomy of C. bergamia. Chemical components of leaf and peel essential oils from C.bergamia, and its close relatives, C. limon, C. aurantifolia and three varieties of C. aurantium,were analyzed by GC and GC-MS. The analytical result shows that the chemical compositions of the leaf essential oils from C. bergamia are basically the same as those from three varieties of C. aurantium. Their main components are linalool (29.19-39.75% )and linalylacetate (24.73-30.24% )etc., and contents of other components are also similar. But theirpeel essential oils are different. The peel essential oils from C. bergamia contain less limonene(29.94%) than those from C. aurantium (92.55-94.31% ) and less beta-pinene (3.00%) andy-terpinene(3.48% )than those from C. limon or C. aurantifolia (respectiyely 9.16% and10.42% ) . The peel essential oils from C. bergamia contain not only as much linalool(22.20%) and linalyl acetate (32.66%)as those in the leaf essential oils from C. aurantium,but also as much limonene(29.94% )as that in the peel essential oils from C. limon or C.aurantifolia . The contents of limonene are close to those of the essential oils from C.aurantifolia. This result shows that C. bergamia may be a natural hybrid between C.aurantium and C. aurantifolia, as proposed by Sinclair W. B.  相似文献

The methods of GC with fused silica capillary column, its Kovats retention index of GC and GC-MS-DS etc. We were used to study the aromatic compounds of the peel essential oil of Citrus sinensis (L.) Osbeck and aromatic concentrates of fruit flesh. 29 chemical constituents from the peels and 40 chemical constituents from the fruit flesh were identified. The trace constituents α-sinensal 0.01% and β-sinensal 0.01% are the special aroma ones for Citrus sinensis. At the same time, the changes flavor components in Citrus sinensis peels and fruit flesh during storage were also explored.  相似文献

Citrus aurantium L. var. amara Engl., is a better species of sour oranges. There are essential oils in the flowers, the peels, the leaves and the branches of C. aurantium. The flower oil can be used in the preparation of perfumes of high quality. The peel oil is used mainly for the flavor-endowing of soft drinks, alcoholic drinks, bread, confectionaries and cakes. In order to control the quality of the essential oils and to improve them, we have systema- tically studied the chemical constituents of the flowers, the leaves and the peals of C. aurantium with our preparation. 12 main components were separated by silica gel column chromatography. The following 33 chemical components were identified by IR, GC-MS and GC retention index: α-thujene, α-pinene, camphene, β-pinene, myrcene, limonene, β-ocimene, trans-linalooloxide (furanoid), cis-linalooloxide (furanoid), linalool, 1,4-p-methadien-7-ol, trans-pinocarveol, camphor, terpinen-4-ol α-terpineol, nerol, citral-b, geraniol, linalylacetate, citrala, trans-linalooloxide (pyranoid), methyl anthranilate, terpinyl acetate, cis-linalooloxide (pyranoid), neryl acetate. geranyl acetate, nonanal, β-caryophyllene, α-humulene, γ-muurolene, β-nerolidol, farnesol, α- nerolidol. GC retention index of 33 compounds were measured. A fast method for routine determination is presented.  相似文献
