Peptic ulceration is among the most prevalent gastrointestinal disorders characterized by pepsin and gastric acid mediated mucosal damage, as result of imbalance between defensive and offensive processes. The main objective of the current study was to investigate the antiulcer potentials of crude methanolic ectract (Ph.Cr) in aspirin induced ulcerogenesis using pylorus ligated rat model. urease and inhibitory potentials were evaluated using standard protocols. All fractions were analyzed using GC-MS to identify major components. The aspirin induced ulcerogenesis in pylorus ligated rat model was associated with significant changes in the mean ulcer score [ = 7.141, = 0.0002], gastric juice volume [ = 8.245, < 0.0001], gastric juice pH [ = 5.715, = 0.0008], free acidity [ = 4.544, = 0.0033], total acidity [ = 2.740, = 0.0373], and pepsin concentration [ = 2.335, = 0.0664]. Pre-treatment with Ph.Cr at 100, 200, and 400 mg/kg dose exhibited marked gastroprotective and anti-ulcerogenic effect in the aspirin induced pyloric ligation ulcerogenesis model at 100, 200, and 400 mg/kg as indicated by ulcerative biochemical parameters. In urease inhibition assay, leaves essential oil (Ph.Lo), saponins (Ph.Sp), and chloroform extract (Ph.Chf) exhibited highest activities with IC of 90, 98, and 520 μg/ml, respectively. Ph.Sp, Ph.Chf, ethyl acetate (Ph.EtAc), and Ph.Cr showed MICs of 25, 30, 32.25, and 40.50 μg/ml, respectively against . Several compounds were identified in GC-MS analysis of samples. Significant antiulcer, urease inhibitory as well as anti-proteus potentials of solvent extracts, signify its potential use for the management of peptic ulcers and may provide scientific bases for the traditional uses of the plant.
消化性溃疡是最常见的胃肠道疾病之一,其特征是胃蛋白酶和胃酸介导的黏膜损伤,这是防御和攻击过程失衡的结果。本研究的主要目的是使用幽门结扎大鼠模型,研究粗甲醇提取物(Ph.Cr)在阿司匹林诱导的溃疡形成中的抗溃疡潜力。使用标准方案评估脲酶和抑制潜力。所有馏分均通过气相色谱-质谱联用(GC-MS)分析以鉴定主要成分。在幽门结扎大鼠模型中,阿司匹林诱导的溃疡形成与平均溃疡评分[ = 7.141, = 0.0002]、胃液体积[ = 8.245, < 0.0001]、胃液pH值[ = 5.715, = 0.0008]、游离酸度[ = 4.544, = 0.0033]、总酸度[ = 2.740, = 0.0373]和胃蛋白酶浓度[ = 2.335, = 0.0664]的显著变化相关。在阿司匹林诱导的幽门结扎溃疡形成模型中,以100、200和400 mg/kg剂量的Ph.Cr预处理表现出显著的胃保护和抗溃疡作用,如溃疡生化参数所示。在脲酶抑制试验中,叶精油(Ph.Lo)、皂苷(Ph.Sp)和氯仿提取物(Ph.Chf)表现出最高活性,IC分别为90、98和520 μg/ml。Ph.Sp、Ph.Chf、乙酸乙酯(Ph.EtAc)和Ph.Cr对 的最低抑菌浓度(MIC)分别为25、30、32.25和40.50 μg/ml。在样品的GC-MS分析中鉴定出了几种化合物。溶剂提取物具有显著的抗溃疡、脲酶抑制以及抗变形杆菌潜力,表明其在消化性溃疡治疗中的潜在用途,并可能为该植物的传统用途提供科学依据。
