Abstract:
The flowers of Jasminum sambac (L.) Ait. are noted for their fresh and delicate pleasant fragrance. We used the XAD-4 (Robin and Haas Co.) hydrophobic resin to absorb the fragrance released from the flowers and had a satisfied result. The Head Space was analysed by means of capillary GC/MS/DS combination and 37 constituents were identified. They are ethyl acetate (0.22%), 3-methyl cyclopentene (0.13%), 2-methyl hexane ( 0.09 % ), 2, 2, 3, 4-tetramethyl petane (0.07 % ), n-heptane (0.03 % ), phenyl- 2-propanone (0.05%), 2-methyl butate (0.03 % ), 3-methyl heptane (0.02%), butyl acetate (0.12 % ), 2-methyl propen-2-1y acetate (0.04 % ), n-hexen-l-ol ( 1.06% ), 6-methyl-2-hepta- none (0.18%), 6-methyl 5-hepten-2-one (0.12%), carbamyl benzoate (0.42%), -pinene ( 0.53 % ), 3- hexenyl acetate ( 13.80 % ), limonene ( 0.12 % ), benzaldehyde ( 1.13 % ), ocimene ( 0.06 % ), methyl benzoate ( 6.27 % ), linalool ( 25.01% ), trans-linalool oxide ( 0.32 % ), benzyl acetate (23.71%), 3-hexenyl butate ( 1.72% ), methyl salicylate (2.55%), cyclohexyl formate (0.10%), indole ( 1.83% ), 2, 6-dimethyl 5-heptenal (0.05%), methyl anthranilate (1.56%), 2, 6-dimethyl heptenal (0.53%), -caryophyllene (0.32%), -farnsene (0.10%), humulene ( 0.21% ), -cadinene (0.62%), cis-caryophyllene ( 13.67% ), trans, trans-farnsol (0.35%), cyclohexyl benzoate ( 3.37% ), respectively.
