Measurement	Jerusalem artichoke extract (%)
	0	25	50	100
DPPH radical scavenging activity (%)	16.60±1.951)d	47.50±2.88c	62.74±0.58b	81.14±2.16a
ABTS radical scavenging activity (%)	15.29±1.39d	32.83±2.68c	49.10±1.40b	71.58±0.88a
Reducing power	0.879±0.03b	0.904±0.01b	1.034±0.00a	1.047±0.02a

All values are mean±SD of triplicate experiments.
Means with different superscript letters in a row are significantly different at p<0.05.
