米糠脂肪烷醇及其在运动饮料中的应用展望

摘要

米糠脂肪烷醇的主要成分为二十八烷醇,二十八烷醇是具有显著抗疲劳功能的天然物质.以力竭游泳实验,通过小鼠行为学指标和生化指标的变化,研究二十八烷醇的抗疲劳功能.实验结果显示,与空白组相比,以米糠脂肪烷醇喂养的低、中、高(50、100、150 mg/(kg·d))三个剂量组小鼠负重游泳时间均有显著延长;同时与空白组相比,负重游泳后,剂量组小鼠血清乳酸,尿素氮含量减少,肝糖原储存量增加.研究表明,米糠脂肪烷醇能够增加小鼠的运动耐力,改善小鼠运动后的多项生化指标,具有抗疲劳功能.%The main component of rice bran fatty alkanol is octacosanol,which is a natural substance with remarkable anti-fatigue function.The anti-fatigue function of octacosanol is studied by loading swimming experiment,which researchs into the behavioral and biochemical indexes of mice.The result shows that,compared with the blank group,the loading swimming time of mice with feeding dose of 50,100,150 mg/(kg·d)of rice bran fatty alkanol is significantly prolonged.At the same time, after loading swimming,serum lactate and the content of urea nitrogen decreased,and the storage of hepatic glycogen increased.The study showed that rice bran fatty alkanol can increase the exercise endurance of mice,improve the biochemical indexes after exercise,and exert anti-fatigue function.
