From: Vanillin production by biotransformation of phenolic compounds in fungus, Aspergillus luchuensis
The mass spectrometry of vanillin glucoside produced during the phenolic biotransformation of Aspergillus luchuensis. The HRESI-mass spectrometry of vanillin glucoside was measured by LC/MS/MS. The accurate molecular formula of vanillin glucoside was determined to be C14H18O8 based on the mass 313.0927 (M-H)−, 313.0926, calcd. for C14H18O8. The other production ions derived from the vanillin (m/z: 161.0588, 177.0557, 180.0426 and 205.0495) were also detected which were structurally supported
