中文摘要: 采用响应面优化超临界CO2萃取美藤果油工艺，并研究其对高强度运动下大鼠腓肠肌功能恢复和ATP酶的影响。结果表明：萃取美藤果油的最优工艺条件为萃取压力21 MPa、萃取温度55℃、萃取时间109 min，此条件下美藤果油的得率为50.15%。大鼠实验表明，灌胃美藤果油后，由于其具有较强的抗氧化能力，可以提高过氧化物酶（peroxidase，POD）活性和琥珀酸脱氢酶（succinate dehydrogenase，SDH）水平，减少乳酸的产生，提高三磷酸腺苷（adenosine triphosphate，ATP）酶合成能力，清除机体内产生的自由基，避免脂质过氧化，缓解运动性疲劳，进而使得大鼠腓肠肌功能恢复。
Abstract:Response surface methodology was used to optimize the supercritical CO2extraction process of Rattan oil，and the effects of the oil on recovery of gastrocnemius muscle function and ATPase after high-intensity exercise were studied.The optimum extraction conditions were determined as extraction pressure of 21 MPa，extraction temperature of 55℃ and extraction time of 109 min.Under these conditions，the yield of Rattan oil was 50.15%.The results showed that after intragastric administration of the oil，the activity of peroxidase and the level of succinate dehydrogenase increased，the production of lactic acid reduced，and the activity of adenosine triphosphate（ATP）increased.This was facilitated by strong antioxidant capacity and ATP synthesis ability，elimination of free radicals produced in the body，avoidance of lipid peroxidation，alleviation of exercise-induced fatigue，and recovery of gastrocnemius function.
