HPLC analysis: Chromatographic condition was RP-C18 column, pH 1.6 in mobile phases, binary solvent delivery gradient elution, and UV-Vis detection was used at 518 nm. Fingerprint: The relative reserving time and relative area of chromatography peaks were computed, and the relative area of chromatography peaks were arranged according to relative reserving time in turn. 14 main peaks were separated and used in fingerprints. The chromatography peaks were identified preliminaryly. By using HPLC method, for the first time, the fourteenth peak was separated and it was found that the relative content of this peaks was relevant to the aging of wine closely. The anthocyanin HPLC fingerprints had a big difference from different vintage Cabernet Gernische wines. The good reproducibility and stability were shown in this experiment. The method of anthocyanin HPLC fingerprints is feasible for distinguishing the age (vintage) of red wine.
