Barberry (Berberis vulgaris) is a well known medicinal plant in Iran and has also been used as food. The antihistaminic and anticholinergic activity of aqueous extract of barberry fruits were investigated on isolated guinea-pig ileum, and dose response curves of histamine and acetylcholine with and without extract were plotted. The pA2 values for antihistaminic activity of extract and dexchlorpheniramine were calculated (extract; pA2 +/- S.E.M. = 4.50 +/- 0.01[-log C (g/l)]; dexchlorpheniramine; pA2 +/- S.E.M. = 9.36 +/- 0.14[-log C (M)]) and compared with each other. The pA2 values for anticholinergic activity of extract and atropine were also calculated (extract, pA2 +/- S.E.M. = 4.37 +/- 0.03[-log C (g/l)]; atropine, pA2 +/- S.E.M. = 8.99 +/- 0.13[-log C (M)]) and compared. The results indicated antihistaminic and anticholinergic activity of extract that seems to be of the competitive type.
伏牛花(小檗)是伊朗一种著名的药用植物,也被用作食物。研究了伏牛花果实水提取物对离体豚鼠回肠的抗组胺和抗胆碱活性,并绘制了有提取物和无提取物时组胺和乙酰胆碱的剂量反应曲线。计算了提取物和右氯苯那敏抗组胺活性的pA2值(提取物;pA2±标准误=4.50±0.01[-log C(g/l)];右氯苯那敏;pA2±标准误=9.36±0.14[-log C(M)])并相互比较。还计算了提取物和阿托品抗胆碱活性的pA2值(提取物,pA2±标准误=4.37±0.03[-log C(g/l)];阿托品,pA2±标准误=8.99±0.13[-log C(M)])并进行比较。结果表明提取物具有抗组胺和抗胆碱活性,似乎属于竞争性类型。
