目的:研究杜仲醇提水溶部位(DT)对小鼠运动及运动后代谢变化的影响。方法:对小鼠负重游泳时间、运动后血清尿素氮、肝糖原、血乳酸含量进行测定。结果:杜仲醇提水溶部位不影响小鼠正常体重。延长负重游泳时间、降低运动后血清尿素氮含量,增加肝糖原含量,降低血乳酸含量。结论:杜仲醇提水溶部位具有抗疲劳作用。 OBJECTIVE: To study the effects of the water-solubilizing fraction (DT) of Eucommia ulmoides on exercise metabolism and post-exercise metabolic changes in mice. Methods: The weight-bearing swimming time, serum urea nitrogen, hepatic glycogen, and blood lactic acid content were measured. RESULTS: The water extract of Eucommia ulmoides did not affect the normal body weight of mice. Extend weight-bearing swimming time, reduce serum urea nitrogen after exercise, increase liver glycogen content, and lower blood lactate content. Conclusion: The water-soluble fraction of Eucommia ulmoides has anti-fatigue effect.
