Eight new 2-(2-phenylethyl)chromone (=2-(2-phenylethyl)-4H-1-benzopyran-4- one) derivatives from aquilaria malaccensis agarwood

摘要

Eight new and eight known 2-(2-phenylethyl)chromone (=2-(2-phenylethyl)-4H- 1-benzopyran-4-one) derivatives, i.e., 1-8 and 9-16, respectively, together with the two known sesquiterpenoids 17 and 18 were isolated from a 70% MeOH extract of Aquilaria malaccensis (AM) agarwood chips. Their structures were determined based on extensive spectroscopic analysis and comparison with reported data.
