Typical analytical LC-DAD chromatogram of anthocyanins enriched extract (AEE) extract recorded at 520 nm, respectively at 280 nm. Identified peaks at 520 nm correspond to Cy-3-O-samb-5-gluc (peak 1), Cy-3,5-digluc (peak 2), Cy-hexoside-pentoside (peak 3), Cy-3-O-samb (peak 4), and Cy-3-O-gluc (peak 5). Unidentified peaks from chromatogram recorded at 280 nm are compounds found in the AEE, after SPE (solid phase extraction) clean-up procedure, more likely phenolic acids.
