Agarwood holds significant importance as a valuable resource for aromatic purposes, however, key components responsible for aroma and the differences between regions and grades remain to be deeply elucidated. Thus, the odors of agarwood sourced from typical zones, as well as the renowned Kynam agarwood, were analyzed by HS-SPME Arrow GC-MS in SCAN and MRM modes. The integrated strategy proposed herein exploits the respective advantages of non-targeted and targeted analysis. In addition to a total of 55 volatile components identified from the NIST database, 114 odor components were matched according to the Smart Aroma Database, and a series of differential compounds was also unearthed and quantified.
