The aim of the present study was to evaluate the anxiolytic properties of the decoction of stem bark of in mice. The decoction of is used in traditional medicine in Cameroon to treat diseases like anxiety disorders, fever, infantile convulsions and malaria.
Stress induced hyperthermia, elevated plus maze, open field and hole-board tests were used. Four different doses of the decoction were administered to mice and their effects were compared to the effects of diazepam and vehicle. Phytochemical characterization of the decoction revealed the presence of alkaloids, flavonoids, tannins and saponins.
Administration of resulted in a significant decrease of stress induced hyperthermia in mice at the doses of 29.5, 59 and 118 mg/kg. In the elevated plus maze test, increased the number of entries and the percentages of entries and time into the open arms, and reduced the number of entries and the percentages of entries and time into the closed arms. In the hole-board test, increased the number of both head-dipping and crossing and decreased the latency to the first head-dips and rearing. The decoction of and diazepam increased locomotion in the open field test.
The number of rearing and the mass of fecal boli produced were decreased in mice treated with decoction and diazepam. In conclusion, the results indicated that decoction of has anxiolytic-like properties in mice and could potentially be used for anxiety treatment.
本研究旨在评估[植物名称]茎皮水煎剂对小鼠的抗焦虑特性。在喀麦隆的传统医学中,[植物名称]水煎剂用于治疗焦虑症、发热、小儿惊厥和疟疾等疾病。
采用应激性体温过高、高架十字迷宫、旷场和洞板试验。给小鼠施用四种不同剂量的水煎剂,并将其效果与地西泮和赋形剂的效果进行比较。水煎剂的植物化学特征显示含有生物碱、黄酮类化合物、单宁和皂苷。
在29.5、59和118mg/kg剂量下,施用[植物名称]水煎剂可使小鼠应激性体温过高显著降低。在高架十字迷宫试验中,[植物名称]水煎剂增加了进入开放臂的次数、进入开放臂的次数百分比和在开放臂停留的时间百分比,并减少了进入封闭臂的次数、进入封闭臂的次数百分比和在封闭臂停留的时间百分比。在洞板试验中,[植物名称]水煎剂增加了探头和穿越的次数,并缩短了首次探头和站立的潜伏期。[植物名称]水煎剂和地西泮在旷场试验中增加了运动能力。
用[植物名称]水煎剂和地西泮处理的小鼠站立次数和粪便团块质量减少。总之,结果表明[植物名称]水煎剂在小鼠中具有抗焦虑样特性,可能可用于焦虑症治疗。
