Figure 6

ABTS-radical scavenging activity of α- and β-carotene crystals at different concentrations. Values are Mean ± SEM of 3 observations. At the 0.05 level, at time intervals 0, 60, 120, 180, 240, and 300 seconds, the difference in superscripts indicates significant difference in means. Superscripts (1) (a, b, c) for 0.001%; (2) (d, e, f) for 0.005%; (3) (g, h, i) for 0.01%; (4) (j, k, l, m) for 0.05%; and (5) (n, o, p) for 0.1% are used.
