Abstract: The volatile fragrance components of Jasminum sambac (L.) Aiton flower were collected by a modified simultaneous steam distillation and solvent extraction apparatus (SDE). The obtained extract was concentrated to 100 μL by the gas entrainment method in which the extract was distilled under reduced pressure with the influence 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 nalkanes were added into extract. 28 compounds were identified. The major components were: linalool, benzyl acetate, ciscaryophyllene, cis-3-benzyl benzoate, methyl anthranilate and indole. These results show the components of the extract have no qualitative difference from absolute oil. The advantages of the above procedure were discussed in detail.

Key words: GC/MS analysis, Simultaneous steam distillation and solvent extraction, Kovats index, Jasminum sambac
