Wounds continue to be a difficult clinical problem, with early and late consequences causing significant morbidity and death. As a result, proper wound management is critical. In addition to contemporary medicine, medicinal herbs serve an essential role in the treatment of wounds and bacterial infections. is a medicinal plant that has traditionally been used to treat wounds. However, there are no scientific reports on solvent fraction wound healing activities. As a result, the current study presents a scientific assessment of the wound healing ability of the solvent fractions of leaves.
The leaves were crushed and macerated three times in 80% methanol. Chloroform, ethyl acetate, and aqueous fractions of simple ointment at 5% w/w and 10 percent w/w strengths were prepared using the fusion technique based on the British Pharmacopoeia. Excision and incision wound models were used to assess the solvent fractions' wound healing activities. The anti-inflammatory efficacy of crude and solvent fractions was tested in mice utilizing a carrageenan-induced hindpaw edema model.
In rats, a test dose of 2000 mg/kg of the 10% w/w crude extract ointment was found to be safe. Groups treated with the 5% and 10% ethyl acetate fractions of the extract experienced significant (p<0.05 and p<0.01) wound reduction in the excision wound model. When compared to the negative control, the length of epithelization in groups treated with 10% ethyl acetate fraction and aqueous fractions of was statistically significant (p 0.001). By lowering the amount of carrageenan-induced paw edema, the leaf extract and the chloroform fraction of demonstrated a dose-dependent anti-inflammatory effect.
The extract showed remarkable wound healing and anti-inflammatory activity and might be recommended for the treatment of many types of human wounds.
伤口仍然是一个棘手的临床问题,其早期和晚期后果会导致严重的发病率和死亡率。因此,正确的伤口处理至关重要。除了现代医学外,草药在伤口和细菌感染的治疗中也起着重要作用。[植物名称]是一种传统上用于治疗伤口的药用植物。然而,关于其溶剂提取物伤口愈合活性尚无科学报道。因此,本研究对[植物名称]叶的溶剂提取物的伤口愈合能力进行了科学评估。
将叶子碾碎并在80%甲醇中浸泡三次。根据英国药典采用融合技术制备了浓度为5% w/w和10% w/w的氯仿、乙酸乙酯和水提取物的简单软膏。采用切除和切开伤口模型评估溶剂提取物的伤口愈合活性。利用角叉菜胶诱导的后爪水肿模型在小鼠中测试粗提取物和溶剂提取物的抗炎效果。
在大鼠中,发现2000 mg/kg的10% w/w粗提取物软膏试验剂量是安全的。在切除伤口模型中,用提取物的5%和10%乙酸乙酯提取物处理的组伤口明显减小(p<0.05和p<0.01)。与阴性对照相比,用10%乙酸乙酯提取物和[植物名称]水提取物处理的组上皮化长度具有统计学意义(p 0.001)。通过降低角叉菜胶诱导的爪水肿量,[植物名称]叶提取物和氯仿提取物表现出剂量依赖性抗炎作用。
该提取物显示出显著的伤口愈合和抗炎活性,可能推荐用于治疗多种类型的人类伤口。
