Radical scavenging activity of ethanolic extract of green and red leaves of Cantigi (Vaccinium varingiaefolium Bl. Miq.)

Indonesia's Cantigi (Vaccinium varingiaefoilum Bl. Miq.) is a member of the blueberry family that grows abundantly around volcanoes. It has two distinct leaf colors, red color leave (RCL) and green color leave (GCL), which contain secondary metabolites including anthocyanins. This study aimed to characterize the antioxidant properties of Cantigi leaf using various methods. DPPH (2,2’-diphenyl-1-picrylhydrazyl), BHA (butyl- hydroxyanisole), and BHT (butyl hydroxytoluene) were used to check the...
