摘要: 以鮟鱇鱼(Lophius litulon)子为原料,利用复合酶解法制备低分子质量肽并对其抗氧化活性进行评价。利用胃蛋白酶和胰蛋白酶对鮟鱇鱼子进行酶解,超滤后得到分子质量小于1 kDa的鮟鱇鱼子肽(MRP),并对其在体外的自由基(DPPH、ABTS及·OH)清除能力进行测定。此外,通过测定细胞活性、MDA、SOD、MDA和GSH-Px水平,研究其对H2O2诱导的RAW 264.7细胞损伤的保护作用。结果表明,MRP对DPPH、ABTS和·OH具有良好的清除作用,且能保护H2O2对RAW 264.7细胞的氧化损伤,可提高细胞活性及细胞中CAT、SOD、GSH-Px的活力,下调MDA的含量水平。结果表明,MRP具有较好的抗氧化能力,可作为添加剂用于抗氧化相关产品研发。

Abstract: The monkfish(Lophius litulon) roe was used as the raw material, the low molecular weight peptide was prepared by complex enzymatic hydrolysis and its antioxidant activity was evaluated. The monkfish roe was hydrolyzed by pepsin and trypsin, respectively. After ultrafiltration, the monkfish roe peptide (MRP) with molecular mass less than 1 kDa was obtained, and its free radicals (DPPH, ABTS, and ·OH) were detected in vitro. In addition, the protective effects of H2O2-induced RAW 264.7 cell damage were studied by measuring the cell vitality, MDA, SOD, MDA and GSH-Px levels. The results showed that MRP had a good scavenging effect on DPPH, ABTS and ·OH, and could protect the oxidative damage of RAW 264.7 cells from H2O2 to a certain extent. MRP could improve the cell activity and the activities of CAT, SOD and GSH-Px, and reduce the level of MDA. In conclusion, our results indicated that MRP had good antioxidant capacity and could be used as an additive in the research and development of anti-oxidation related products.

Key words: monkfish (Lophius litulon) roe, low molecular mass peptides, H2O2, RAW 264.7 cell, antioxidant
