Abstract

ABSTRACTBiotransformation of linalool was studied using grape must and three strains of Botrytis cinerea (5901/2; 5909/1; 5899/4). Capillary gas chromatography and combined capillary gas chromatography‐mass spectrometry revealed predominant conversion (>90%) of linalool to (E)‐2,6‐dimethyl‐2,7‐octadiene‐1,6‐diol. in minor concentrations (<10%), the corresponding (Z)‐isomer, 2‐vinyl‐2‐methyl‐tetrahydro‐ furan‐5‐one, the four (E)‐and (Z)‐linalool oxides in their furanoid and pyranoid forms, the (E)‐ and (Z)‐acetates of pyranoid linalool oxides as well as 3,9‐epoxy‐p‐menth‐ 1 ‐ene identified.
