GAE= Gallic acid equivalent, QE= Quercetin equivalent, DE=Diosgenin equivalent, w=Weight. AA= Antioxidant activity, MCC= Metal chelating capacity, AAE= Ascorbic acid equivalent, W. fruit = Whole fruit. Each value is presented as mean ± standard deviation. Means in a column with the same letter superscripts are not significantly different (P > 0.05, Tukey's test), whereas those with different letter superscripts are significantly different (P < 0.05, Tukey's test).
