Antioxidant activity of G. alypum leaves.

IC50 (mg/mL)	Ascorbic Acid	Soxhlet	Sonication	Maceration
ABTS scavenging assay	0.06 ± 0.02 b	0.25 ± 0.01 d	0.18 ± 0.00 c	0.04 ± 0.01 a
β-carotene	0.59 ± 0.00 c	0.65 ± 0.05 d	0.28 ± 0.09 b	0.15 ± 0.00 a

Results of the ANOVA test are significantly different at p < 0.05, and each data point is represented by the average of three repetitions ± SD of one independent experiment. IC₅₀: half maximal inhibitory concentration. Values with different superscripts within the same column are significantly different (p < 0.05).
