Anthocyanins in Fruits ofPassiflora edulisandP. suberosa

Abstract The analysis of anthocyanin pigments in the passion fruit Passiflora edulis and in the highly colored fruits of P. suberosa was performed using combinations of chromatographic and spectroscopic techniques. In addition to cyanidin 3-glucoside (97%), small amounts of cyanidin 3-(6″-malonylglucoside) (2%) and pelargonidin 3-glucoside (1%) were found in the rind of the passion fruit. The 3-(6″-malonylglucoside) and 3-glucoside of cyanidin, delphinidin, petunidin, and pelargonidin were identified in extracts of P. suberosa. Anthocyanins acylated with malonic acid constituted 27% of the total anthocyanin content in this latter species.
