Abstract: Phenolic components from the peel and flesh of Malania oleifera Chun were extracted by reflux extraction and their antioxidant activities were studied. The extraction rate of polyphneols was 3.29% after twice-repeated extractions for 1 h each time with pH 4 HCl solution at a solid-to-liquid ratio of 1:30 (g/mL) in 70 ℃ water bath. The extract obtained under these conditions showed strong scavenging effect on hydroxyl and DPPH free radicals and the maximum scavenging rates were 74.00% and 76.54%, respectively. A ranking of the extraction, ascorbic acid and tannic acid in decreasing order of DPPH free radical scavenging activity was observed.

Key words: Malania oleifera Chun, extraction, polyphenols, antioxidation
