摘要
目的小补心汤(XBXT)由代赭石、旋覆花、竹叶和淡豆豉4味中药组成,文献记载其有缓解抑郁情绪的作用。本实验研究其总黄酮提取物(XBXT-2)是否具有抗抑郁作用。方法采用大、小鼠强迫游泳模型和大鼠获得性无助模型观察XBXT-2的抗抑郁作用,采用酶联免疫法检测获得性无助大鼠血清皮质酮水平,并观察XBXT-2对小鼠自发活动的影响。结果单次灌胃给予XBXT-2 50和100mg.kg-1可以显著缩短小鼠和大鼠强迫游泳的不动时间。连续4 d灌胃给予XBXT-2 25和50 mg.kg-1可以显著减少获得性无助模型大鼠的逃避失败次数,并显著降低其血清皮质酮水平。XBXT-2 50 ~200 mg.kg-1对正常小鼠的自发活动性无明显影响。结论 XBXT-2在抑郁动物模型上具有抗抑郁样作用,其机制可能与其抑制下丘脑-垂体-肾上腺轴功能亢进有关。
