is an important medicinal plant that is used in a traditional system for its curative properties such as analgesic potency, antipyretic, anti-inflammatory, sedation potential, and antidepressant and cure of diseases such as skin diseases. This study deals with the isolation of two flavonoids namely spinacetin (1) and patuletin (2) from chloroform fraction of The isolated compound spinacetin (1) and patuletin (2) were screened for anti-inflammatory, analgesic, sedative, and muscle relaxant effects. Compounds 1 and 2 were assessed against hot plate-induced noxious stimuli at various doses which showed excellent ( < 0.05) analgesic effect in a dose-dependent manner. The muscle relaxant activity was determined by traction and inclined screening model, both compounds showed significant muscle relaxant activity with time. The sedative potential of isolated compounds 1 and 2 was determined by the open field model, both compounds showed good sedation ( < 0.05) at 20 mg/kg. The anti-inflammatory potential of compound 1 was recorded by histamine-induced paw edema and carrageen paw edema model, and in both models, compounds 1 and 2 showed strong effect at 20 mg/kg. Binding orientations, binding energy values, and computed inhibition constants (Ki) values revealed that the studied compounds have a good to excellent inhibition potential against -opioid receptors and COX-2.
是一种重要的药用植物,在传统医学体系中因其具有止痛效力、解热、抗炎、镇静潜力、抗抑郁等治疗特性以及可治疗皮肤病等疾病而被使用。本研究涉及从[植物名称]的氯仿馏分中分离出两种黄酮类化合物,即菠菜黄素(1)和紫铆亭(2)。对分离出的化合物菠菜黄素(1)和紫铆亭(2)进行了抗炎、止痛、镇静和肌肉松弛作用的筛选。化合物1和2在不同剂量下针对热板诱导的有害刺激进行评估,结果显示出良好的(<0.05)剂量依赖性止痛效果。通过牵引和倾斜筛选模型测定肌肉松弛活性,两种化合物均随时间显示出显著的肌肉松弛活性。通过旷场模型测定分离出的化合物1和2的镇静潜力,两种化合物在20mg/kg时均显示出良好的镇静作用(<0.05)。通过组胺诱导的爪肿胀和角叉菜胶爪肿胀模型记录化合物1的抗炎潜力,在这两种模型中,化合物1和2在20mg/kg时均显示出强效作用。结合方向、结合能值和计算得到的抑制常数(Ki)值表明,所研究的化合物对μ-阿片受体和COX-2具有良好至优异的抑制潜力。
