文章: class =“ sub_abstract_label”>背景: 传统上用来治疗炎症,疼痛和发烧的Vernoia杏仁核(VA)的年轻和老叶子。但是,年轻的功效d旧叶子用于治疗这些疾病的尚未比较。对VA的年轻(乙基)和旧(乙醇)叶片的乙醇提取物进行了定性植物化学筛选。在Carrageenan诱导的大鼠炎症模型中评估了口服乙醇和乙醇(50-200 mg/kg)和双氯芬酸(10 mg/kg)的抗炎活性。乙醇,乙醇和阿司匹林(25 mg/kg)的抗染料活性在面包师酵母诱导的Pyrexia模型中进行了评估。通过将大鼠发炎的爪子插入冷水中,评估了两种提取物的抗合成作用。使用尾部戒断和福尔马林引起的伤害感受测试评估提取物的抗伤害感受特性。爪子的组织病理学检查除了福尔马林测试外,还了解提取物的作用机理。 Negative control rats received 2 ml/kg normal saline in all tests.RESULTS: The amount of flavonoids, alkaloids, tannins, and phenolics were significantly (p < 0.05) higher in EthOL than EthYL, while saponins were significantly higher (p < 0.05) in EthYL than Ethol。乙醇的抗氧化能力和总抗氧化能力明显高(p <0.05)。但是,这显着(P <0.05)低于抗坏血酸的抗氧化活性。与标准药物相似,在乙醇和乙醇中观察到抗炎,抗热和抗伤害感受特性的剂量依赖性增加。在阴性对照中观察到肥大细胞脱粒,伴随着血管舒张和高白细胞增多,但在提取物治疗组中明显低。两种提取都介导了他们的algesic effect through opioidergic and nitric oxide pathways with EthYL additionally implicating the muscarinic cholinergic system.
CONCLUSION: Although both EthYL and EthOL alleviate inflammation, pyrexia and nociception, EthYL of VA was found to be more potent than Ethol。
