Evaluation of Phenolic Content and Free Radical Scavenging Activity of Indonesia Wild Honey Collected from Seven Different Regions

Abstract

Several wild honey samples collected from seven different regions in Indonesia were investigated to determine their total phenolic content, flavonoid content, and free radical scavenging activity by analyzing the 1,1-diphenyl-2-picrylhydrazyl (DDPH) radical and phenolic profile. Rutin, (+)-catechin, ferulic acid, and galangin were found to be the major phenolic compounds of Indonesia wild honey. The total phenolic content significantly correlated with the total flavonoid content (p=0.000) and the percentage of DPPH radical scavenging activity (p=0.000). Results indicated that there are different polyphenol profiles among the different regions.
