has traditionally been used as a poultice to alleviate local inflammation and painful diseases. This study aimed to evaluate the anti-inflammatory, wound-healing, analgesic, and antipyretic potential of its ethanol extract (PAAPEE) for the first time. antioxidant assays of using a 2,2-diphenyl-1-picrylhydrazyl assay revealed that it showed IC of 62.50 ± 6.85 μg/mL in contrast to standard, ascorbic acid, that showed IC of 85.51 ± 0.38 μg/mL. Administration of PAAPEE at a dose of 500 mg/kg (PAAPEE-500) displayed 78.44% and 75.13% inhibition of paw edema in carrageenen and histamine-induced edema models. respectively, 6 h post-treatment compared to that of the untreated group. Furthermore, it showed 68.78% inhibition of Freund's complete adjuvant-induced edema 21 days after treatment. It reduced the animal's rectal temperature in the yeast-induced fever model to 99.45 during the fourth h post-treatment. It significantly inhibited abnormal writhing by 44% in the acetic acid-induced pain model. PAE-500 also showed enhancement in wound closure by 72.52% with respect to that of the untreated group on the 10th day post-treatment using the excision healing of wound model. Histopathological examination of skin samples confirmed this improvement, showing enhanced tissue architecture with minimal infiltration of inflammatory cells. High-performance liquid chromatography (HPLC) of PAAPEE revealed the presence of quercetin, gallic, -coumaric, benzoic, chlorogenic, syringic, ferulic, cinnamic, and sinapic acids. Molecular docking of 5-lipoxygenase and glycogen synthase kinase-3 protein indicated their potential interaction within the active sites of both enzymes. Thus, serves as an effective natural wound-healing, anti-inflammatory, analgesic, and antipyretic agent.
传统上一直被用作膏药来减轻局部炎症和疼痛性疾病。本研究旨在首次评估其乙醇提取物(PAAPEE)的抗炎、伤口愈合、镇痛和解热潜力。使用2,2-二苯基-1-苦基肼测定法进行的抗氧化测定表明,与标准品抗坏血酸相比,其IC50为62.50±6.85μg/mL,而抗坏血酸的IC50为85.51±0.38μg/mL。以500mg/kg的剂量(PAAPEE-500)给予PAAPEE,在角叉菜胶和组胺诱导的水肿模型中,治疗后6小时分别显示出78.44%和75.13%的爪部水肿抑制率。此外,在治疗21天后,它显示出对弗氏完全佐剂诱导的水肿有68.78%的抑制率。在酵母诱导的发热模型中,治疗后第4小时,它将动物的直肠温度降至99.45。在醋酸诱导的疼痛模型中,它显著抑制异常扭体反应达44%。在使用伤口切除愈合模型治疗后第10天,PAE-500相对于未治疗组,伤口闭合率也提高了72.52%。皮肤样本的组织病理学检查证实了这种改善,显示组织结构增强,炎症细胞浸润最少。PAAPEE的高效液相色谱(HPLC)显示存在槲皮素、没食子酸、对香豆酸、苯甲酸、绿原酸、丁香酸、阿魏酸、肉桂酸和芥子酸。5-脂氧合酶和糖原合酶激酶-3蛋白的分子对接表明它们在两种酶的活性位点内有潜在相互作用。因此,PAAPEE可作为一种有效的天然伤口愈合、抗炎、镇痛和解热剂。
