Malaria, caused by Plasmodium parasites, is a global health concern. Natural products, such as plant extracts, are investigated for new antimalarial agents. Spondias mombin, traditionally used for medicinal purposes, was examined for its effects on parasitemia, hematological parameters, antioxidant activities, liver function biomarkers, and serum electrolytes in Plasmodium berghei-infected mice. Mice received varying doses of the ethylacetate extract. Various dosages of the extract and the prescribed medication dramatically slowed the parasite's growth. The extract significantly improved red blood cell (RBC) and platelet counts, particularly at higher doses. Hemoglobin levels were decreased dose-dependently. Antioxidant analysis showed increased superoxide dismutase (SOD), glutathione peroxidase (GPx), and reduced catalase (CAT) activities and malondialdehyde (MDA) levels, indicating robust antioxidant properties. Liver function tests showed mixed effects, with elevated aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin (TB) levels at some doses, yet decreased alanine aminotransferase (ALT) at the highest dose, suggesting possible hepatoprotective effects. Serum electrolyte levels remained stable. Seventy-eight (78) bioactive components were identified in the extract by gas chromatography-mass spectrometry (GC-MS) analysis. The extract demonstrated substantial antimalarial and antioxidant capacities, with minimal liver stress and stable electrolyte levels, suggesting safety as an adjunct therapy for malaria. Further research is needed to ascertain the specific antimalarial bioactive constituents and their mechanisms of action.
由疟原虫引起的疟疾是一个全球关注的健康问题。天然产物,如植物提取物,正被研究用于寻找新的抗疟药物。传统上用于药用的腰果树被研究了其对感染伯氏疟原虫小鼠的寄生虫血症、血液学参数、抗氧化活性、肝功能生物标志物和血清电解质的影响。小鼠接受了不同剂量的乙酸乙酯提取物。提取物和规定药物的不同剂量显著减缓了寄生虫的生长。提取物显著改善了红细胞(RBC)和血小板计数,尤其是在高剂量时。血红蛋白水平呈剂量依赖性下降。抗氧化分析表明,超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GPx)活性增加,过氧化氢酶(CAT)活性降低,丙二醛(MDA)水平升高,表明具有强大的抗氧化特性。肝功能测试显示出混合效应,某些剂量下天冬氨酸转氨酶(AST)、碱性磷酸酶(ALP)和总胆红素(TB)水平升高,但最高剂量下丙氨酸转氨酶(ALT)降低,表明可能具有肝脏保护作用。血清电解质水平保持稳定。通过气相色谱 - 质谱(GC - MS)分析在提取物中鉴定出78种生物活性成分。该提取物显示出显著的抗疟和抗氧化能力,对肝脏的压力最小且电解质水平稳定,表明作为疟疾辅助治疗药物具有安全性。需要进一步研究以确定具体的抗疟生物活性成分及其作用机制。
