HS-GC-MS analysis of volatile components in imported agilawood.

The volatile components of 10 agarwood samples from 5 countries (Kalimantan, Malaysia, Bangladesh, India, Indonesia) were analyzed by headspace gas chromatography-mass spectrometry (HS-GC-MS). The results showed that the volatile components of 10 agarwood samples were mainly aromatic and sesquiterpe-noids. The types and relative contents of volatile components of agarwood samples with the same origin but different morphology were different. The volatile components of the samples also showed certain differences. The mannene and (+) -cyclodecene were only detected in the agarwood samples of Malaysia and could be used as the characteristic components of the agarwood in the producing area; a-cluene and β-Guaiacrox were only detected in Indonesian agarwood samples and could be used as the characteristic component of the agarwood in this area; (+)-α-long-leafene and a-carboene were only detected in Indian agarwood samples and could be used as the characteristic component of agarwood in this area; the types and contents of alcohols in agarwood samples from Indonesia were significantly lower than those in other places. The results could provide a new idea for the rapid detection and identification of the agarwood production area. [ABSTRACT FROM AUTHOR]
