In order to explore the polymeric 2-(2-phenylethyl) chromones (PPECs) components and the structures from agarwood (Aquilaria spp.), ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass/mass spectrometry (UPLC-Q-TOF-MS) was used to acquire the spectrum of TOF-MS and TOF-MS/MS of agarwood samples. The fragmentation pathway of PPECs was analyzed. The screening and structure confirmation of PPECs from agarwood was performed. A total of 55 PPECs components were identified. According to the structural characteristics, 55 components were grouped into three types, including dimeric 2-(2-phenylethyl) chromones (DPECs), trimeric 2-(2-phenylethyl) chromones (TPECs) and sesquiterpenoid-2-(2-phenylethyl) chromones (SPECs). All identified components were consisted of 44 DPECs, 3 TPECs and 8 SPECs, of which nine DPECs, one TPECs and one SPECs were firstly identified in agarwood. Furthermore, 2-4 isomers were observed for some PPECs components from agarwood. The results showed that agarwood were rich in PPECs components and the corresponding isomers. Meanwhile, the proportion of DPECs was the highest (80%) among total PPECs. The results could provide reference for the study of material basis of pharmacodynamics effect and utilization of agarwod.
