Screening of Marine Natural Products on Inhibitory Effect of the Formation of Lipid Peroxidation

수산생물자원 추출물의 과산화지질생성의 억제효과

The methanolic extracts of some marine natural products were tested for investigating the effects on the formation of lipid peroxide and the activities of free radical generating enzymes. The methanolic extracts of Styela clava, Ecklonia stolonifera, Pachymeniopsis elliptica and Hypnea charoides which decreased the formation of lipid peroxide inhibited the activity of xanthine oxidase about 41, 20, 20 and 21% by adding $100\;{\mu}g/ml$ of each methanolic extracts, respectively. However, the four extracts didn't inhibit the activity of aldehyde oxidase.
