3.2. Antioxidant capacity
The ripe durian had the highest amounts of antioxidant capacity
and bioactive compounds (Table 5). FRAP absorption
measurements (Fig. 3 A and B) showed that durian at the
ripe stage had higher antioxidant activity than the other two
samples.
A very good correlation was observed between the antioxidant
capacities determined by FRAP and CUPRAC (Fig. 4, A
and B) and the total polyphenols (R2 is 0.972 and 0.891,
respectively). The correlation coefficients between the antioxidant
capacity determined by FRAP and CUPRAC and for flavonoids
(Fig. 4 A and B) were lower than for total polyphenols
