Total anthocyanin content in pomegranate extracts was
measured using the pH differential method (Fuleki and Francis,
1968). The absorbance was measured spectrophotometrically at
510 and 700 nm in buffers at pH 1.0 and 4.5, using A = [(A510–
A700)pH1.0 (A510––A00)pH4.5]. The results were expressed as mg of
cyanidin-3-glucoside equivalents per 100 g of fresh weight (mg Cya
3100 g-1fw).
