Free radical scavenging activity v1 [PDF]

open access: yes, 2018
Free radical scavenging assay was measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical test. To each aqueous extract 3 mL of 0.1 mM solution of DPPH in methanol was added (Fermont, Monterrey). Tubes were shaken vigorously and allowed to stand for 30 min at room temperature in the dark. Absorbance was measured at 517 nm.
