The volatile compositions of the Agarwoods from different production places were extracted by solid phase microextraction(SPME),and isolated and identified by GC-MS,then the quality of Agarwood was evaluated.The investigation showed that the Agarwoods from different places were all consisted of sesquiterpenoids and aromatic compounds,but their chemical compositions and contents were quite different.The six characteristic components,including 4-phenyl-2-butanone, p-methoxybenzylacetone, agarospirol,agarofuran,hinesol and baimuxinal,and their contents were used as the evaluation indexes for the quality of the Agarwoods. The results indicated that the contents of characteristic constituents in Laos Agarwood were the highest(about 20%),the contents in the Cambodian Agarwood were the second(17%),while the contents in the Chinese Agarwoods(Hainan and Dongguan) were the lowest. Therefore,the Laos Agarwood had the best quality,the Cambodian Agarwood was slightly poorer, and they both were superior to the Chinese Agarwood. The method showed the advantages of low sample consumption and strong characteristic.
