摘要: 目的通过给SD大鼠灌喂石榴汁,研究其体重增加和粪便及盲肠内容中鞣花酸及尿石素A含量,为深层次研究鞣花酸及尿石素A的生物学作用提供数据支持。方法选择24只平均体重为(169.08±7.88)g的雄性SD大鼠,随机分为3组,每组8只,分别为对照组、试验Ⅰ组和试验Ⅱ组。在相同日粮基础上,试验Ⅰ组大鼠每天每只灌喂1.5 mL石榴汁,试验Ⅱ组大鼠每天每只灌喂3.0 mL石榴汁,并获取大鼠体重数据及采集粪便及盲肠内容物样品。结果①试验Ⅱ组大鼠日增重显著(P<0.05)高于对照组,比对照组高36.32%;②灌喂石榴汁显著(P<0.05)增加大鼠粪便鞣花酸和尿石素A的含量;③灌喂石榴汁后,试验Ⅰ组和试验Ⅱ组大鼠盲肠中鞣花酸和尿石素A的含量均极显著(P<0.01)高于对照组。结论给大鼠灌喂石榴汁可以显著提高大鼠体重,显著或极显著提高大鼠粪便和盲肠内容中鞣花酸和尿石素A的含量,且灌喂3 mL/(只·d)效果最佳。

Abstract: [Objective] To determine whether feeding pomegranate juice would have effect on body weight and content of ellagic acid and urolithin A in feces and cecum contents in SD rats, and to provide data support for the in-depth study on biological effects of ellagic acid and urolithin A. [Method] A total of 24 male SD rats with an average body weight of (169.08±7.88) g were randomly divided into 3 groups (control group, test groupⅠand test groupⅡ) with 8 rats in each group. All of the excremental rats fed the same basal diet. The rats in test groupⅠand Ⅱ were fed with 1.5 mL and 3.0 mL of pomegranate juice per day, respectively. The rats were weighted and their feces and cecum contents were sampled. [Result] The daily weight gain of the rats in test group Ⅱ was increased by 36.32% (P<0.05) compared to the control group. Feeding pomegranate juice significantly (P<0.05) increased the content of ellagic acid and urolithin A in feces of rats, and extremely significantly (P<0.01) increased the content of ellagic acid and urolithin A in cecum contents of rats. [Conclusion] Feeding pomegranate juice for rats has significant or extremely significant effects on increasing the body weight and content of ellagic acid and urolithin A in feces and cecum contents, and the best effect was observed in the feeding volume of 3 mL per day per rat.
