In a biological system the product of free-radical induced-lipid peroxidation are conjugated dienes (CDs), lipid peroxides and malondialdehyde (MDA). Its control depends on antioxidant activities. Antioxidant defend the body system by controlling the damage caused by the free radicals. This paper describes lipid peroxidation process and antioxidant activities present in three species of holothuroid obtained from the coastal waters of Terengganu, Malaysia. Among the three species studied, the coelomic fluid of Bohadschia mamorata vitiensis contained the highest level of protein (7.24 + 0.04)g/L. The coelomic fluid of Stichopus badionotus Selenka contained the highest level of superoxide dismutase (SOD) (9.46 + 0.99)X 105 IU/g protein, MDA (16.46 + 1.28)nmol/g protein and total antioxidant activities (AOA) (58.81 + 5.70) %. In Stichopus variegatus Semper the coelomic fluid only demonstrated the highest level of CDs (94.19 + 11.34) RU/g protein compared with the other two species. This preliminary study indicated that some form of antioxidant activities are present in the coelomic fluid of holothuroids.
在生物系统中，自由基诱导的脂质过氧化产物包括共轭二烯（CDs）、脂质过氧化物和丙二醛（MDA）。其控制取决于抗氧化活性。抗氧化剂通过控制自由基造成的损害来保护身体系统。本文描述了从马来西亚登嘉楼沿海水域获得的三种海参的脂质过氧化过程和抗氧化活性。在所研究的三种海参中，巴氏白尼参的体腔液蛋白质含量最高（7.24 + 0.04）g/L。棘辐肛参的体腔液中超氧化物歧化酶（SOD）含量最高（9.46 + 0.99）×105 IU/g蛋白质、MDA含量最高（16.46 + 1.28）nmol/g蛋白质以及总抗氧化活性（AOA）最高（58.81 + 5.70）%。与其他两种海参相比，花刺参的体腔液仅显示出共轭二烯含量最高（94.19 + 11.34）RU/g蛋白质。这项初步研究表明，海参体腔液中存在某种形式的抗氧化活性。
