| Abstract | We research the development of natural preservatives or functional foods. Here Omija(Schijandra chinensis Baillon) was extracted with distilled water and 70%(v/v) ethanol, and extracts were tested for biological(antibacterial, antioxidative, and fibrino lytic) activities. The polyphenol contents of water and ethanol extracts were 511.5 and 696.6 mg/100 g of Omija, respectively. The water and ethanol extracts from Omija demonstrated antibacterial activity against Listeria monocytogenes and Staphylococcus aureus. The electron-donating abilities(EDAs) of the water and ethanol extracts were 88.6% and 94.5% at 1,000 ppm. The superoxide dismutase(SOD)-like activities of the water and ethanol extracts were 51.2% and 53.6% at 1,000 ppm. The nitrite scavenging abilities(NSAs) of the water and ethanol extract were 70.2% and 76.2% at 1,000 ppm, and were the highest at pH 1.2. The higher antibacterial and antioxidative activities were seen in the ethanol extract, which also had a higher polyphenol content than did the water extract. However, fibrinolytic activities of the water extract were higher than those of the ethanol extract, at all dilutions in the range (v/v). We conclude that extracts of Omija can be used for health food development or natural preservatives in processed foods. |
