J Asian Nat Prod Res. 2010 Feb;12(2):134-7. doi: 10.1080/10286020903508424.

Abstract

Two new 2-(2-phenylethyl)chromones, (5S(*),6R(*),7S(*))-5,6,7-trihydroxy-2-(3-hydroxy-4-methoxyphenethyl)-5,6,7,8-tetrahydro-4H-chromen-4-one (1) and (5S(*),6R(*),7R(*))-5,6,7-trihydroxy-2-(3-hydroxy-4-methoxyphenethyl)-5,6,7,8-tetrahydro-4H-chromen-4-one (2), were isolated from the Chinese eaglewood of Aquilaria sinensis (Lour.) Gilg. Their structures were established by detailed MS and NMR spectroscopic analysis, as well as comparison with the literature data.
