中文摘要:

      目的 以鲜芦根与荷叶的提取液为原料, 研制鲜芦根荷叶复合饮料, 并考察其对小鼠运动耐力的影响。方法 基于单因素试验结果, 釆用Box-Benhnken与正交试验设计原理对复合饮料的配方参数进行优化, 并通过动物实验考察其对小鼠运动耐力的影响。结果 鲜芦根荷叶复合饮料的最佳配方为: 鲜芦根提取液用量27%、荷叶提取液用量31%、赤藓糖醇用量4%、柠檬酸用量0.2%、羧甲基纤维素钠用量0.08%、黄原胶用量0.03%、海藻酸钠用量0.05%。不同剂量的鲜芦根荷叶复合饮料均可明显延长小鼠的爬杆时间(P<0.01), 显著增强体内乳酸脱氢酶活力(P<0.01), 并显著减少体内乳酸含量(P<0.01)。结论 所得鲜芦根荷叶复合饮料呈淡红色、酸甜适宜, 具有鲜芦根与荷叶的混合香味, 形态均一、稳定, 有利于提高机体的运动耐力。

英文摘要:

      Objective To develop compound beverage of Rhizoma phragmitis and Lotus leaf with Rhizoma phragmitis and Lotus leaf as the raw materials, and study the effect of its athletic stamina in mice. Methods The formula parameters of compound beverage was optimized by Box-Benhnken and orthogonal test design based on the single factor test result. Animal experiment was conducted to investigate its effect on athletic stamina in mice. Results The optimal formula of the compound beverage was: 27% of Rhizoma phragmitis extract liquid, 31% of Lotus leaf extract liquid, 4% of erythritol, 0.2% of citric acid, 0.08% of sodium carboxymethylcellulose, 0.03% of xanthan gum, and 0.05% of sodium alginate. The compound beverage at different gavage dosage could all obviously prolong the climbing time in mice (P<0.01), dramatically increase the activity of lactic dehydrogenase (P<0.01), and significantly decrease lactic acid content in vivo (P<0.01). Conclusion The compound beverage of Rhizoma phragmitis and Lotus leaf presented light red, moderate acidity and sweetness with mixed fragrance of Rhizoma phragmitis and Lotus leaf, homogeneous and stable of solution character, and can improve athletic stamina in mice.
