【摘要】 研究制备了感官良好的百合枸杞发酵液,分析了百合枸杞发酵液的主要成分,并利用小鼠跑台力竭实验、负重游泳力竭实验和生化指标测定实验,研究百合枸杞发酵液对机体的抗运动疲劳作用。结果表明:百合枸杞发酵液的功效成分为多糖(232.21±5.33)mg/100 g,总黄酮(23.22±1.32)g/100 g,总氨基酸(88.3±5.23)g/100 g,植物乳杆菌(Lactobacillus plantarum)(7.53±0.42)Log10 cfu/100 g。经过30 d的灌胃喂养,与空白对照组相比,低(5 g/kg·d)、中(10 g/kg·d)和高剂量组(15 g/kg·d)均能显著地提高小鼠的跑台力竭时间、负重游泳首次下沉时间和力竭时间,并且中、高剂量组能够明显地降低血清尿素氮和血乳酸的含量(p<0.05),而对肝糖原含量的提高作用则并不显著(p>0.05)。由此可知:百合枸杞发酵液具有良好的抗运动疲劳作用。更多还原

【Abstract】 In this study, the lily wolfberry fermented liquid with desirable sensorial characteristics was prepared. The functional component of lily wolfberry fermented liquid was analyzed. Further, the treadmill test and weight-loaded swimming test and biochemical index determination experiment were used to study the effects on anti-exercise-fatigue of lily wolfberry fermented liquid. The result showed that the content of polysaccharide, flavonoid, total amino acid and Lactobacillus plantarum in lily wolfberry fermented liquid was(232.21±5.33) mg/100 g,(23.22±1.32) g/100 g,(88.3±5.23) g/100 and(7.53±0.42) Log10 cfu/100 g, respectively. After intragastric administration for 30 d, the exhaustive time of treadmill and weight-loaded swimming, and the down time for the first time of low(5 g/kg/d), medium(105 g/kg/d) and high dose group(15 g/kg/d) were significantly extended(p<0.05) compared with the control group. The content of serum urea nitrogen and blood lactic acid of medium and high dose group were significantly reduced(p<0.05). In addition, the effect on increase of hepatic glycogen of lily wolfberry fermented liquid was not significant(p>0.05). The study indicated that lily wolfberry fermented liquid had a good resistance to movement fatigue.更多还原
