IC₅₀ (mg/mL) of antioxidant properties of the methanolic extracts from Northern Morocco (MA) and Portugal (PT).

Assays			A. mellea	M. procera
A.	DPPH radical-scavenging activity	MA	1.06 ± 0.12 *	1.19 ± 0.05 ns
		PT	1.32 ± 0.09 *	1.31 ± 0.05 ns
B.	β-carotene/linoleate assay	MA	0.43 ± 0.01 ***	0.16 ± 0.03 **
		PT	0.53 ± 0.01 ***	0.09 ± 0.02 **
C.	Ferricyanide/Prussian blue assay	MA	0.52 ± 0.02 ***	0.96 ± 0.01 ***
