Bignay [Antidesma bunius (L.) Spreng.] fruits were used in the preparation of red wine. Must and wine
samples at different stages of processing were analyzed for total antioxidant activity (TAA), total
phenolics (TP), total flavonoids (TF) and total anthocyanins (TA). Ranges in values obtained were as
follows: 53.37 ± 0.57 to 78.35 ± 2.12% for TAA, 651.39 ± 3.09 to 930.07 ± 26.18 mg L-1 gallic acid
equivalents for TP, 371.62 ± 5.84 to 703.67 ± 12.80 mg L-1
catechin equivalents for TF, and 96.97 ± 4.72
to 372.62 ± 4.77 mg L-1 cyanidin-3,5-diglucoside for TA. Results indicated that changes in the TAA of
the must/wine samples varied during the different stages in the processing of bignay wine. These
changes could not be completely attributed to a certain group of phenolic compounds as the changes
in TP, TF and TA also varied from one stage to another.
