Confirmation of the identity of stilbenoids by LC-UV-ESIMS(−) in methanolic extract of thiamine-treated plants (partial chromatogram). (A) UV chromatogram at 307 nm, which permits the detection of stilbene derivatives specifically. (B) Extracted Ion Chromatogram of m/z 227.0703 corresponding to resveratrol derivatives (mass formula: C14H11O3). (C) Extracted Ion Chromatogram of m/z 389.1231 corresponding to piceide isomers (mass formula: C20H21O8). (D) Extracted Ion Chromatogram of m/z 453.1333 corresponding to viniferins (mass formula: C28H21O6).
