To evaluate the antimalarial effect of aqueous methanolic extract and solvent fractions of leaves against in mice model.
leaves were extracted with 80% methanol and dried. The dried crude extract was then defatted and further fractionated with chloroform, ethyl acetate, and butanol. Acute oral toxicity test was performed as per the Organization for Economic Cooperation and Development guideline 425. Peter's 4-day suppressive test was used to determine the antimalarial activity of the extract and fractions.
The crude leaf extract of leaves against < 0.001) chemosuppression compared to the negative control. Both the extract and fractions were able to prevent induced body weight loss and body temperature reduction and also increased the survival time of the mice as compared to the negative control. The aqueous methanolic leaf extract of leaves were extracted with 80% methanol and dried. The dried crude extract was then defatted and further fractionated with chloroform, ethyl acetate, and butanol. Acute oral toxicity test was performed as per the Organization for Economic Cooperation and Development guideline 425. Peter's 4-day suppressive test was used to determine the.
The extracts of leaves showed promising antimalarial activity, with no sign of toxicity and therefore may support its traditional use for the treatment of malaria. leaves were extracted with 80% methanol and dried.

在小鼠模型中评估叶的甲醇水提取物及其溶剂萃取物的抗疟效果。
叶用80%甲醇提取并干燥。然后将干燥的粗提取物脱脂,并用氯仿、乙酸乙酯和正丁醇进一步分离。按照经济合作与发展组织指南425进行急性经口毒性试验。采用彼得4天抑制试验来测定提取物及其萃取物的抗疟活性。
与阴性对照相比,叶的粗叶提取物对疟原虫有显著的化学抑制作用(P<0.001)。与阴性对照相比,提取物及其萃取物均能防止疟原虫诱导的体重减轻和体温降低,还能延长小鼠的存活时间。叶的甲醇水提取物用80%甲醇提取并干燥。然后将干燥的粗提取物脱脂,并用氯仿、乙酸乙酯和正丁醇进一步分离。按照经济合作与发展组织指南425进行急性经口毒性试验。采用彼得4天抑制试验来测定……
叶提取物显示出有前景的抗疟活性,且无毒性迹象,因此可能支持其在传统医学中用于治疗疟疾。叶用80%甲醇提取并干燥。然后将干燥的粗提取物脱脂,并用氯仿、乙酸乙酯和正丁醇进一步分离。按照经济合作与发展组织指南425进行急性经口毒性试验。采用彼得4天抑制试验来测定……
