目的：觀察復(fù)方低聚原花青素（OPC）的抗疲勞作用。方法：進(jìn)行復(fù)方OPC粉對(duì)小鼠游泳時(shí)間以及對(duì)小鼠血清尿素、血乳酸、肝糖原的影響測(cè)定。結(jié)果：ig給予復(fù)方OPC，能明顯延長(zhǎng)小鼠游泳時(shí)間，降低小鼠血清尿素和血乳酸的量（P＜0.01），而提高肝糖原的量（P＜0.01）。結(jié)論：復(fù)方OPC能夠調(diào)整體內(nèi)代謝，快速恢復(fù)體力，是具有明顯的抗疲勞作用的新型健康食品。

Objective: To study the antifatigue effect of compound pracyanidolic oligomers (OPC). Methods: The effect of compound OPC on swimming time of mice was observed. The effects on the content of the urea, lactatic acid, and liver glycogen were studied, respectively. Results: Compound OPC could enhance the swimming durability of mice.The content of both urea and lactatic acid was decreased, but the content of liver glycogen was increased. Conclusion: Compound OPC has obvious antifatigue effects. The mechanisms maybe associates with increasing the activities of antioxidation enzymes and preventing lipid peroxidation in tissues.
