Antioxidant capacity and half-maximal effective concentration (EC₅₀) of free radical scavenging activity of AP crude extracts.

Crude Extract	ABTS Scavenging Activity		DPPH Scavenging Activity
	mg VCEAC/g Dry Weight	EC50 (mg/mL)	mg VCEAC/g Dry Weight	EC50 (mg/mL)
APH	0.92 ± 0.12 a	>8	0.99 ± 0.08 a, b	>8
APE	1.57 ± 0.04	3.11 ± 0.05	1.27 ± 0.04 a, c	12.61 ± 3.47
APW	2.47 ± 0.06 a	1.06 ± 0.04	1.88 ± 0.25 b, c	3.62 ± 0.35

The data are expressed as mean ± SEM (n = 3). The same superscript letters in the same column indicate a significant difference between the means by one-way ANOVA (p < 0.05).
