Free Radical Scavengers Inhibit Light-Dependent Degradation of the 32 kDa Photosystem II Reaction Center Protein

, 1990
Involvement of oxygen-free radicals in the rapid, light-dependent degradation of the 32 kDa photosystem II reaction center protein was investigated. The free radical scavengers propyl-gallate and uric acid inhibited 32 kDa protein degradation without ...

Free radical scavenging activity v1 [PDF]

, 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.
