Values are expressed as mean ± standard error of mean (n = 6), ^acompared to the negative control, ^bcompared to the 400 mg/kg MeOH extract, and ^ccompared to the positive control. MeOH: 80% methanol extract; Lop 3: 3 mg/kg loperamide; CF: chloroform fraction; HF: hexane fraction; AF: aqueous fraction. Controls were given 10 ml/kg distilled water (for aqueous fraction) and 10 mk/kg of 2% Tween 80 (for chloroform fraction, hexane fraction, and crude extract). ¹P < 0.05, ²P < 0.01, and ³P < 0.001.
