Investigation of the hot water extract of fruiting bodies of the wood‐rotting fungus Gloeophyllum odoratum (Wulf. ex Fr.) Imazeki [syn. Osmoporus odoratus (Wulf. ex Fr.) Singer, Trametes odorata (Wulf.) Fr.] led to the identification of 16 aromatic compounds which are possibly biogenetically derived from the ligin of the host tree. Their structures were identified by gas chromatography, mass spectrometry and NMR spectroscopy. Some of them were identified after conversion to their trimethylsilyl derivatives. The constituents described for the first time as constituents of G. odoratum are 4‐methoxybenzaldehyde, 4‐hydroxybenzaldehyde, 4‐methoxyphenylacetaldehyde, 2‐(4′‐methoxyphenyl)‐ethanol, 2‐(4′‐hydroxyphenyl)‐ethanol, 2‐(3′‐hydroxy‐4′‐methoxyphenyl)‐ethanol, 4‐methoxybenzylalcohol, 2‐hydroxy‐4′‐methoxyacetophenone, methyl 4‐methoxymandelate, methyl 3‐hydroxy‐4‐methoxymandelate, methyl 3‐hydroxy‐4‐methoxyphenylacetate, methyl 3,4‐dimethoxyphenylacetate, 4‐methoxyphenylacetic acid, methyl 4‐hydroxyphenylacetate and 3‐hydroxy‐4‐methoxyphenylacetic acid. In addition, the known compound methyl 4‐methoxyphenylacetate was isolated. Apparently, the pleasant odour of G. odoratum is caused by some of these compounds. Copyright © 2000 John Wiley & Sons, Ltd.
