低咖啡因普洱茶提取物的促进消化功能实验研究

Low-caffeine Pu-erh Tea Extracts Promote Digestion in Animals

目的:通过大鼠体重、体重增重、摄食量、食物利用率和消化酶测定实验,以及小鼠小肠运动实验来评价低咖啡因普洱茶提取物促进动物消化功能。方法:通过优化普洱茶提取工艺得到低咖啡因普洱茶提取物。依据保健食品促进消化功能评价方法设计大、小鼠实验,实验结束时测定大鼠的体重、体重增重、摄食量、食物利用率、1 h胃液量、胃蛋白酶活性和排出量,以及小鼠的墨汁推进率。结果:与对照组相比,普洱茶提取物高剂量组大鼠的1 h胃液量和胃蛋白酶排出量增加(P<0.05,P<0.01);中、高剂量组小鼠的墨汁推进率转换值升高(P<0.01)。结论:此低咖啡因普洱茶提取物具有促进动物消化的功能,具有一定的开发价值。

Objective To objectively appraise the promoting digestion function of low - caffeine Pu - erh Tea extract through rat tests for body weight, weight gain, food intake, digestive enzymes, food utilization rate and mouse test for small intestinal movenlent. Methods The low - caffeine Pu - erh Tea extracts were obtained by optimize the Pu - erh Teag extraction process. We designed experiments according to lhe evaluation melhod of promoting digestion on health food. We measured 1he body weight, weight gain, food intake, digestive enzymes, food utilization rate in rat tests and ink propelling rates in mouse small intestinal movenlent test respectively. Results The rat tests showed that the gastric juice within one hour and gastric pepsin output of low - caffeine Pu - erh Tea extract group with high dose were increased compared with the control group （P 〈 0. 05, P 〈 0. 01 ）. The mouse test showed that the ink propelling rates of low - caffeine Pu - erh Tea extract groups with middle and high dose were increased compared with the model control group （ P 〈 0. 01 ）. Conclusions This study suggests that the low - caffeine Pu - erh Tea extract can promote digestion in animals, have certain development application value.
