摘要：
A major novel coumarin metabolite was isolated from rat hepatic microsomal incubations by high-performance liquid chromatography. In the presence of a rat liver cytosolic fraction and NADH it was rapidly metabolized to o-hydroxyphenylethanol. The metabolite co-chromatographed with an authentic sample of o-hydroxyphenylacetaldehyde and its identity was confirmed by mass spectral analysis. The formation of o-hydroxyphenyl acetaldehyde from coumarin was NADPH-dependent. It was the major metabolite formed by rat, gerbil and human liver microsomes at a coumarin concentration of 1mM. © 1991.
