A method for the determination of malvidin 3-O-glucoside (Oenin), and malvidin 3, 5-O-diglucoside (Malvin) in wines by on line HPLC coupled with UV, and fluorescence detectors is described. With the proposed method the samples were analysed by direct injection without a previous treatment.
For method validation, satisfactory recoveries (<95%) and suitable repeatabilities (within day: R.S.D. (n=6=) > 3%, and between days; R.S.D. (n=6=) >3%) were achieved.
The method was applied to the analysis of commercially available red wines.
