|
Black raspberry, blueberry, mulberry and black chokeberry are excellent source of natural antioxidant. These berries have the various antioxidant substances such as pigments (anthocyanins), polyphenols, etc. Especially, polyphenols have potential health effects which are the protection of liver and cardiovascular diseases. Therefore, the objectives of this research were to compare the difference in chemical properties and antioxidative effects of the various black fruits. For total antioxidant activity and DPPH radical scavenging activity, samples were prepared to extract using distilled water and 80% ethanol, and freeze-dried. Total antioxidant activities of both of extracts (water and 80% EtOH) were increased depending on the concentration of extracts (250, 500, 750 and 1,000 ug/mL).
