Table 6. DPPH and ABTS⁺ radical scavenging activities of plum juice and vinegar

	Sample
	Plum juice	Plum vinegar	Apple vinegar1)
DPPH radical	20.57±4.382)b3)	51.90±0.97a	9.96±1.72c
ABTS+ radical	89.93±0.96a	89.03±0.69b	54.38±0.27c

Commercial apple vinegar was used as a control for antioxidant activity comparison.
All values are mean±SD (n=3).
Means with different superscript letters (^a-c) in the same row are significantly different at p<0.05 by Duncan’s multiple range test.
