Phenolic content and free radical scavenging activities in rambutan during fruit maturation
The 1,1-diphenyl-2-picrylhydrazyl (DPPH•) scavenging activity, changes and accumulation of phenolic content were studied in the peel, seed and pulp of rambutan, Nephelium lappaceum L. (Rongrien and Seeechompoo cultivars) during fruit maturation. The IC50 values of the radical scavenging activity of...
