Despite a substantial scientific progress over the past two decades, malaria continues to be a worldwide burden. Evergrowing resistance towards the currently available antimalarial drugs is a challenge to combat malaria. Medicinal plants are a promising source of new drugs to tackle this problem. Thus, the present study aimed at evaluating the antiplasmodial activity of in infected mice.
A 4-day suppressive test was employed to evaluate the antimalarial effect of 80% methanol and aqueous bark extracts of against in Swiss albino mice.
The acute toxicity test indicated that both extracts of against < 0.001) compared to negative control. The maximum level of chemosuppression (60.2%) was exhibited at 400 mg/kg dose of 80% methanol extract. Moreover, the 80% methanol extract showed a significant ( < 0.001) compared to negative control. The maximum level of chemosuppression (60.2%) was exhibited at 400 mg/kg dose of 80% methanol extract. Moreover, the 80% methanol extract showed a significant (.
The present study indicated that hydromethanolic and aqueous bark extracts of possess a promising antimalarial activity, with higher effect exhibited by the hydromethanolic extract. against.
尽管在过去二十年里取得了重大科学进展，但疟疾仍然是一个全球性负担。对现有抗疟药物的耐药性不断增加是抗击疟疾的一项挑战。药用植物是解决这一问题的有前景的新药来源。因此，本研究旨在评估[植物名称]在感染小鼠体内的抗疟原虫活性。
采用4天抑制试验来评估[植物名称]80%甲醇提取物和树皮水提取物对瑞士白化小鼠体内疟原虫的抗疟效果。
[植物名称]的急性毒性试验表明，两种提取物对[疟原虫名称]的半数致死量均>4000 mg/kg，表明与阴性对照相比毒性较低（P<0.001）。80%甲醇提取物在400 mg/kg剂量时表现出最大化学抑制水平（60.2%）。此外，与阴性对照相比，80%甲醇提取物显示出显著差异（P<0.001）。80%甲醇提取物在400 mg/kg剂量时表现出最大化学抑制水平（60.2%）。此外，80%甲醇提取物显示出显著差异（P<0.001）。
本研究表明，[植物名称]的甲醇水提取物和树皮水提取物具有良好的抗疟活性，其中甲醇水提取物的效果更佳。对[疟原虫名称]有效。
