The volatile compositions of agarwood were produced by biological,chemical and physical(flame drilled) methods,then enriched by solid phase microextraction and isolated and identified by GC-MS.The quality of the agarwood produced was evaluated.Investigation showed that the volatile compositions of the agarwood were all composed of sesquiterpenoids and aromatic compounds,but the chemical compositions and contents of the agarwood were quite different because of the different artificial inducing methods.The six characteristic components,i.e.agarofuran,hinesol,4-phenyl-2-butanone,p-methoxybenzylacetone,agarospirol and baimuxinal,and their contents were used as the evaluation indexes for the agarwood quality.The content of agarospirol in the flame drilled agarwood was the highest,which was about 5.5%.The total content of characteristic components in the agarwood produced by biological method was the highest,which reached to 16.6%,followed by that of the flame drilled agarwood,which was around 13.6%,and the agarwood produced by chemical method was the lowest.The result showed the biological method has the best agarwood quality,the flame drilled method was slightly poor,and they were both superior to the chemical method.
