摘要：
Bioconversion of alpha-damascone (compound 1) was studied with four strains of Botrytis cinerea in grape must (pH 3.2). As biotransformation products of compound 1, 3-oxo-alpha-damascone, cis- and trans-3-hydroxy-alpha-damascone, gamma-damascenone, 3-oxo-8, 9-dihydro-alpha-damascone, and cis- and trans-3-hydroxy-8,9-dihydro-alpha-damascone were identified. In addition, acid-catalyzed chemical transformation of compound 1 to the diastereomers of 9-hydroxy-8,9-dihydro-alpha-damascone was observed. Identifications were performed by capillary gas chromatography (HRGC) and coupled HRGC techniques, i.e., on-line HRGC-mass spectrometry and HRGC-Fourier transform infrared spectroscopy, after extractive sample preparation.
