Abstract: This plant is widely cultivated in southeastern and southern China. The concrete and absolute got from their flower are used in perfumery industry. It is also used popularly as ornamental plant and sometimes as medicine. The main chemical components of the absolute have been determined by the methods of chromatography, GC-MS, IR and NMR. The quantitative determination of these components was carried out by GLC also. The result is as follows: 3-hexenyl acetate 1.09%, cis-3-hcxen-l-ol 1.40%, dipentene oxide 1.09%, linalool 14.33%, methyl benzoate 2.96%, benzyl acetate 11.04%, benzyl alcohol 10.12%, cadinene 4.67%, hexenylbenzoat 16.51%, methyl anthranilate 0.62%, octadecene 6.54%, methyl oleate 2.02%, methyl' octadeca-9-ynoate 0.62%. Three minor components have been determined also.
