In this research antidiabetic, analgesic and antiulcer potential of traditional ethnomedicinal plant: Emex spinosa (L.) Campd. (Family Polygonaceae) was evaluated by extracting its phytoconstituents using methanol (MeOH) solvent through maceration protocol. The quantitative phytochemical analysis of the extract revealed flavonoids were highest in leaf extract (15.63±0.93 mg/mL) and with (11.5±0.57 mg/mL) in stem. Alkaloids and tanins were also present in the samples in various conc. while saponins were absent. To confirm pharmaceutical potential of plant against ulcer, diabetes and analgesic infirmities, a model experimental animal wistar albino rats (Rattus norvegicus) were used. In antiulcer study, using hot plate method the maximum results were observed with 250 mg/kg in the 2.5 hours of study. The leaf extract showed a 40.41±2.73 latency time and the fruit with a 36.77±2.41, and the stem with a 27.85±3.09, which was comparable to the standard drug Aspirin, i.e., 47.5±0.57. For analysis of antiulcer potential of the plants parts doses of 250 and 500 mg/kg was applied to check the reclamation of ethanol-induced acute ulcer and of Aspirin-induced chronic ulcer of stomach. In order to confirm efficacy of the drug potential of plant following parameters like microscopic evaluation, gastric volume, total acidity, mucosa weight, ulcer index, pH and histopathology of stomach were analyzed. In antidiabetic analysis, in an acute study after a single dose of 500 mg/kg extract after 2hrs the blood glucose levels were 367±51.09958NS, 416±59.79548NS, 437.5±61.96437NS mg/dL for leaf, stem and fruit, respectively. After4hrs 351.75±88.27644NS mg/dl, 448.25±25.64948NS mg/dl, 445.25±27.07205NS mg/dl and after 6hrs 354.5±92.70428NS, 442±24.60691NS, a440±33.16625NS mg/dl, respectively. The analgesic activity was explored by applying hot plate, tail flick and formalin paw licking method. In hot plate method the maximum results were observed with 250mg/kg in the 2.5 hours of study. The leaf extract showed a 40.41±2.73 latency time and the fruit with a 36.77±2.41 and the stem with a 27.85±3.09, which was comparable to the standard drug Aspirin, i.e., 47.5±0.57. The respective plant extracts at 250mg/kg showed a gradual rise in latency time when compared to the control. It was concluded that all three components of E. spinosa perform proved to be significant as potential source of herbal medicines to cure different prevalently occurring diseases. Furthermore, it was confirmed through results analysis that plant t can be used to discover novel drug using dedicated high throughput techniques and ethnopharmacological approaches.
在这项研究中,评估了传统草药学植物:Emex spinosa(L.)Campd.(Polygonaceae 科)的抗糖尿病、镇痛和抗溃疡潜力,方法是使用甲醇(MeOH)溶剂通过浸渍法提取其植物成分。提取物的定量植物化学分析显示,叶提取物中的黄酮类化合物含量最高(15.63±0.93mg/mL),茎提取物中的黄酮类化合物含量为(11.5±0.57mg/mL)。生物碱和单宁也存在于各种浓度的样品中,而皂苷则不存在。为了证实植物在治疗溃疡、糖尿病和镇痛方面的药用潜力,使用了 Wistar 白化大鼠(Rattus norvegicus)作为实验动物模型。在抗溃疡研究中,使用热板法,在 2.5 小时的研究中,观察到 250mg/kg 的最大结果。叶提取物显示出 40.41±2.73 的潜伏期,果实为 36.77±2.41,茎为 27.85±3.09,与标准药物阿司匹林(即 47.5±0.57)相当。为了分析植物各部分的抗溃疡潜力,应用 250 和 500mg/kg 的剂量来检查乙醇诱导的急性溃疡和阿司匹林诱导的慢性胃溃疡的恢复情况。为了确认药物的疗效,分析了药物的潜在作用,如显微镜评估、胃容量、总酸度、粘膜重量、溃疡指数、pH 值和胃组织病理学。在急性研究中,在单次剂量为 500mg/kg 提取物后 2 小时,血糖水平分别为 367±51.09958NS、416±59.79548NS、437.5±61.96437NSmg/dL,叶、茎和果实的血糖水平分别为 367±51.09958NS、416±59.79548NS、437.5±61.96437NSmg/dL。4 小时后分别为 351.75±88.27644NSmg/dl、448.25±25.64948NSmg/dl、445.25±27.07205NSmg/dl,6 小时后分别为 354.5±92.70428NSmg/dl、442±24.60691NSmg/dl、a440±33.16625NSmg/dl。通过应用热板、尾巴敲击和福尔马林足舔舐方法,研究了镇痛活性。在热板法中,在 2.5 小时的研究中,观察到 250mg/kg 的最大结果。叶提取物显示出 40.41±2.73 的潜伏期,果实为 36.77±2.41,茎为 27.85±3.09,与标准药物阿司匹林(即 47.5±0.57)相当。各植物提取物在 250mg/kg 时与对照相比潜伏期逐渐延长。研究结果表明,E.spinosa 的三个成分都表现出作为治疗各种常见疾病的草药的潜在来源的显著作用。此外,通过结果分析证实,该植物可以通过专门的高通量技术和民族药理学方法用于发现新的药物。
