研究北方养殖刺参的主要活性成分和对运动小鼠抗疲劳的作用。结果表明:养殖刺参体壁富含酸性黏多糖、胶原蛋白、活性氨基酸和活性脂质等多种活性成分,能提高小鼠负重游泳能力、肝糖元含量和安静状态下小鼠血红蛋白含量,保持运动小鼠血红蛋白水平稳定,显著降低运动小鼠血乳酸的生成,促进运动后血乳酸的消除,加速运动血清尿素氮的清除。说明养殖刺参具有显著的抗疲劳和提高运动耐力的作用。

Abstract :This paper describes the bioactive composition of cultured sea cucumber Stichopus japonicus and its anti-fatigue effect in mice. The results indicated that body wall of S. japonicus was rich in acidic mucopolysaccharides, collagen, bioactive amino acids and lipids. In comparison with the control group, administration of Stichopus japonicus for 30 consecutive days prolonged the duration of exhaustive swimming in mice weighted with weights (approximately 5% of body weight), promoted the synthesis of liver glycogen and hemoglobin and kept a level of hemoglobin 90 min post-swimming similar to that before swimming, significantly decreased the generation of blood lactic acid and accelerated the elimination of blood lactic acid and blood urea nitrogen in mice after swimming. Based on these investigations, S. japonicus has an obvious anti-fatigue effect and improves exercise endurance in mice.

运动性疲劳既与体内内源性物质的消耗有关,也与神经、内分泌以及免疫系统的平衡调节相关。海参为棘皮动物门(Echinodermata)海参纲(Holothuroidea)楯手目(Aspidochirota)动物,是海洋中重要的食物和药物资源。现已证明,海参体壁中含有海参多糖、海参皂苷、海参胶原蛋白肽、海参脑苷酯、神经节苷酯等多种生物活性物质[1],这些活性物质作为生物信息分子对人类生理功能的调节起着重要的信号转导作用,具有提高免疫功能、抗肿瘤、抗凝血、抗血栓、降血脂、抗衰老等多种生理功效[2-5]。海参的种类和来源不同,因生活环境和所摄食物各异,致使其营养成分和功效存有差异。本实验拟在前期工作的基础上,以北方养殖刺参为研究对象,分析养殖刺参的主要成分及其对运动小鼠抗疲劳作用的影响,以期为养殖刺参的深度开发利用提供参考。……
