Distinction of the C-glycosylflavone isomer pairs orientin/isoorientin and vitexin/isovitexin using HPLC-MS exact mass measurement and in-source CID.
Phytochem. Anal. 16(5) , 295-301, (2005) HPLC-MS using collision induced dissociation (CID) has been utilised for the identification of the C-glycosylflavone isomer pairs orientin/isoorientin and vitexin/isovitexin. HPLC-CID/MS analyses produced pseudo-MS/MS spectra that allowed the identification o... |
