Simultaneous determination of multiple active 2‐(2‐phenylethyl)chromone analogues in agarwood by HPLC, QAMS, and UPLC‐MS

Introduction Chromones are the major constituents of agarwood and are considered to be directly related to its quality. Agarotetrol, a chromone derivative, is a Chinese Pharmacopoeia content detection index. However, comprehensive high‐performance liquid chromatography (HPLC), quantitative analysis of multiple components by a single marker (QAMS), and ultra‐performance liquid chromatography mass spectrometry (UPLC‐MS) analyses of this...
