Abstract

Objective: To study the chromones of Aquilariae Lignum Resinatum.Methods: Various chromatographic techniques were used to isolate the chromones of Aquilariae Lignum Resinatum,their structures were identified by analysis of their spectral data,physical and chemical properties.Results: Five compounds were obtained and identified as 6-hydroxy-2-【2-(4′-methoxyphenyl)ethyl】chromone(Ⅰ),6-hydroxy-2-(2-phenylethyl)chromone(Ⅱ),6-hydroxy-7-methoxy-2-(2-phenylethyl)chromone(Ⅲ),6-hydroxy-2-【2-(4′-hydroxyphenyl)ethyl】chromone(Ⅳ),6,7-dimethoxy-2-【2-(4′-methoxyphenyl)ethyl】chromone(Ⅴ).Conclusion:Compounds Ⅲ and Ⅳ were obtained from this plant for the first time.
