Phytochemical Analysis and Study of Antioxidant and Antimicrobial Activities of Two Parts of Cupressus arizonica Essential Oils

Table 3

Antioxidant activity of the two EOs evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays.

Essential oil	DPPH (IC50 = mg/mL)	FRAP (EC50 = mg/mL)
Cone EO	0.098 ± 0.008	0.646 ± 0.02
Leaf EO	5.297 ± 0.09	2.335 ± 0.36
Ascorbic acid	0.00364 ± 0.001	0.0190 ± 0.004

Results are average value ± SD of triplicate measurement. The values in the same line with different letters are significantly different () by Tukey’s multiple range tests.
