Table 1.

EC₅₀ values (μg/mL) of superoxide anion ( ${O_{2}}^{\cdot -}$ ), hypochlorous acid (HOCl) and nitric oxide (NO^•) scavenging capacity by olive leaf extract and ascorbic acid.

	Olive leaf extract (n = 6)	Ascorbic acid (n = 4)
Superoxide anion ( ${O_{2}}^{\cdot -}$ )	52.6 ± 2.1^a	59.3 ± 9.2^a
Hypochlorous acid (HOCl)	714.1 ± 31.4^a	27.3 ± 1.3^b
Nitric oxide (NO^•)	48.4 ± 6.8^a	43.9 ± 8.8^a

EC₅₀, effective concentration, the concentration required to decrease the oxidative effect of reactive species by 50%.

Values are expressed as mean ± standard deviation.

Means with different letters in the same line were significantly different (P < 0.05).
