Material	ABTS radical scavenging activity
	at 250 μg/mL (%)	IC50 (μg/mL)
	70% EtOH	32.9±0.8c1)2)	465.8±2.5d
Hexane	29.3±0.0b	894.0±26.4e
EtOAc	94.8±0.2e	42.9±9.5b
BuOH	72.3±0.3d	117.7±3.7c
H2O	19.9±0.2a	967.4±6.6f
Vit. C3)	100.0±0.0	7.5±0.1a
BHT	98.5±0.1f	57.4±1.1b

Values are expressed as mean±SD of triplicate measurements.
Values with different letters (a-f) in the column are significantly different at p<0.05 according to Duncan's multiple range test.
Positive control: Vit. C, ascorbic acid; BHT, dibutyl hydroxy toluene.
