【摘要】：为考察黄皮果胶的抗疲劳功效,首先采用微波辅助法提取黄皮果胶,通过正交试验获得最优工艺条件为:微波功率600W,提取时间8min,液、料比30∶1,pH值2.0,果胶得率3.61%,总半乳糖醛酸质量分数为78.75%。然后将小鼠分组,分别对其灌胃不同剂量的黄皮果胶,测其体质量,并通过力竭游泳实验,对小鼠的力竭游泳时间,以及血酸、丙二醛、血尿素氮、乳酸脱氢酶、肝/肌糖原等生化指标进行了检测。结果表明:小鼠果胶灌胃2周后,其体质量随果胶剂量的增大而增加,力竭游泳时间随果胶剂量的增大而延长,高剂量时可延长47.95%,具有显著差异。力竭游泳后,小鼠血乳酸、丙二醛和血尿素氮的值均随灌胃果胶量的增加而减小,且高剂量组与对照组有显著差异;而乳酸脱氢酶活力及肝/肌糖原的值则随灌胃果胶量的增加而增大,且中剂量组和高剂量组分别与对照组有显著和极显著差异。黄皮果胶可以有效延缓运动性疲劳,具有良好的抗疲劳功效。
[Abstract]:In order to investigate the anti-fatigue effect of yellow peel pectin, the microwave assisted method was used to extract the pectin. The optimum technological conditions were obtained by orthogonal test: microwave power 600W, extraction time 8min, liquid. The pH value is 2.0, the pectin yield is 3.61 and the total galacturonic acid content is 78.75. Then the mice were divided into groups, and their body weight was measured by different doses of pectin. The exhaustive swimming time, blood acid, malondialdehyde (MDA), blood urea nitrogen, lactate dehydrogenase (LDH) were measured by exhaustive swimming test. Liver / muscle glycogen and other biochemical indexes were detected. The results showed that the body mass of mice increased with the increase of pectin dosage 2 weeks later, and the exhaustive swimming time was prolonged with the increase of pectin dose, and 47.95% with high dose. After exhaustive swimming, the values of blood lactic acid, malondialdehyde and blood urea nitrogen decreased with the increase of the amount of pectin, and there was significant difference between the high dose group and the control group. However, the activity of lactate dehydrogenase and the value of liver / muscle glycogen increased with the increase of pectin dosage, and there were significant differences between the middle and high dose groups and the control group, respectively. Yellow pectin can effectively delay exercise fatigue, has a good anti-fatigue effect.
