Table 1. Total phenolic content and antioxidant activities of loquat leaf extract (LE) and ascorbic acid (AA)

Treatment	Loquat leaf extract	Ascorbic acid
Total phenolic content (μg GAE/mL)	533.38±5.49	NE
DPPH radical scavenging activity (IC₅₀ value mg/mL)	0.06±0.00^b	0.10±0.00^a
ABTS radical scavenging activity (IC₅₀ value mg/mL)	2.87±0.04^a	0.61±0.01^b
Metal chelating activity (IC₅₀ value mg/mL)	5.71±0.03	NE

All values are mean±SE of three replicates.
Means within a row with different letters are significantly different.
GAE, gallic acid equivalents; NE, values were not estimated; DPPH, 1,1-diphenyl-2-picrylhydarzyl; ABTS, 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid).
