ABSTRACT
Objective To analyze similarities and differences of volatile components of Dalbergiae Odoriferae Lignum(DOL) and its adulterants,so as to provide a scientific basis for the identification of the authenticity of the pros and cons of DOL,and offer the reference for the further study of DOL. Methods With headspace solid phase microextraction(HS-SPME)combined with gas chromatography-mass spectrometry(GC-MS),volatile components of DOL and its adulterants were analyzed and identified,and the relative content of each component was calculated by area normalization method. Results There were 70 compounds detected,in which 38 compounds were identified. They were mainly alkenes,alcohols,aldehydes and ketones. A total of 42 compounds were de?tected from DOL volatile components,and 25 components were identified,accounting for 96.54% of the volatile components;28 peaks were detected from its adulterants,and 19 compounds were identified,accounting for 80.7%of the volatile components. Con?clusion There were huge differences in volatile components between DOL and its adulterants. Only 6 common components were de?fected both in the DOL and it's adulterants,with their quite different contents. The main component of DOL was nerolidol,accounting for 61.47%of volatile components;the main component of its adulterants was beta selinene,accounting for 59.04%of total volatile components. The present result provides a scientific guidance for the identification of true or false DOL and also a reference for the fur?ther development of Dalbergia wood.
