摘　　要：目的:探讨高山红景天的主要成分红景天多糖对电刺激离体蟾蜍腓肠肌疲劳的影响。方法:采用脉冲式电流直接刺激离体蟾蜍腓肠肌作为疲劳模型,观察肌肉收缩力、达最大收缩力所需时间以及肌肉收缩持续时间的变化。结果:高山红景天多糖不仅能使肌肉持续收缩时间延长(P<0.01),而且可缩短肌肉达最大收缩所需的时间(P<0.05)。结论:高山红景天多糖具有抗疲劳作用。Objective：To investigate the effect of Rhodiola Sachalinensis A Bor（BSAB） polysaccharide on gastrocnemius fatigue in vitro induced by electric stimulation to Toad. Methods： Isolated toad gastrocnemius stimulated by electricity as the fatigue model, the duration and amplitude of muscle contraction were recorded. Results：The course of muscle maximal contraction were shortened （P〈0. 05） and muscle continuous contraction was prolonged （P〈0.01） after treatment of RSAB polysaccharide. Conclusion： RSAB polysaccharide has an anti fatigue.
