【摘要】 用一种经过改进的“同时蒸馏-萃取”仪提取了茉莉花的香成分,以 GC/MS 和 Kovats保留指数法鉴定了提取物中的28个化学成分。主要成分为:芳樟醇、乙酸苯甲酯、顺-石竹萜烯、榧烯醇、苯甲酸顺-3-己烯酯、邻氨基苯甲酸甲酯、二十三烯-11及吲哚。讨论了鲜花香成分和植物精油的采集与分析方法。更多还原

【Abstract】 The volatile fragrance components of Jasminum sambae (L.) Aiton flo- wer were collected by a modified simultaneous steam distillation and solvent extraction apparatus (SDE).The obtained extract was concentrated to 100 μl by the gas entrain- ment method in which the extract was distilled under reduced pressure with the influ- ence of a steam of nitrogen.The concentrate was analyzed by GC-MS with PEG-20 M capillary column,and the Kovats indexes were determined at the same time whereby the n-alkanes were added into extract.28 compounds were identified.The major compone- nts were: linalool,benzyl acetate,cis-caryophyllene,cis-3-benzyl benzoate,methyl an- thranflate and indole.These results show the components of the extract have no qualita- tive difference from absolute oil.The advantages of the above procedure were discussed in detail.更多还原
