UPLC–qTOF–HR-MS analyses of methylated stilbene, flavanone, and flavone produced by bioconversion using DHS2001/SaOMT2. a UPLC–qTOF–HR-MS chromatogram selected for m/z = 243.1016, 257.1172, and 271.1329 corresponding to desoxyrhapontigenin (P1), 5-hydroxy-3,4′-dimethoxystilbene (P2), and 3,5,4′-trimethoxystilbene (P3), respectively, of culture extracts obtained from DHS2001/SaOMT2 supplemented with resveratrol. b UPLC–qTOF–HR-MS chromatogram selected for m/z = 287.0914 corresponding to sakuranetin (P4), m/z = 301.1071 corresponding to 5-hydroxy-7,4′-dimethoxyflavanone (P5) and 4′-hydroxy-5,7-dimethoxyflavanone (P6), and m/z = 315.1227 corresponding to 5,7,4′-trimethoxyflavanone (P7) of culture extracts obtained from DHS2001/SaOMT2 supplemented with naringenin. c UPLC–qTOF–HR-MS chromatogram selected for m/z = 285.0757, 299.0914, and 313.1071 corresponding to genkwanin (P8), 5-hydroxy-7,4′-dimethoxyflavone (P9), and 5,7,4′-trimethoxyflavone (P10), respectively, of culture extracts obtained from DHS2001/SaOMT2 supplemented with apigenin
