Abstract

The radical scavenging activity of pineapple (A. ananas) was determined by DPPH assay. The dry pineapple fruit was extracted by maceration in Hexane, Dichloromethane and Methanol for 3 days per each and then filtered. The filtrate was evaporated to dryness. The crude extract was mixed with 22,2-diphenyl-1-picrylhydrazyl (DPPH), absorbance at 515 nm. Gallic acid was used as reference standard. The methanol extract showed the most DPPH assay with the percentage of inhibition at 96.91. Pineapple could be used in the food and pharmaceutical industries.
