Helminthosis is one of the greatest causes of parasitic disease and loss in animal productivity. As such, the control of helminth parasites is of critical importance. This study was aimed to investigate the in vitro anthelmintic activity of G. Baker (Annonaceae) fruits against Using in vitro techniques, the anthelmintic activity of extracts and fractions of G. Baker (Annonaceae) was evaluated for ovicidal (Egg hatch inhibition test) and larvicidal (larval mortality test) activity. Besides, the maximum tolerated dose was determined in adult albino rats administered, 300, 400, and 500 mg/kg body weight of the CME fraction, and observed over a period of 48 h for signs of toxicity and mortality. Phytochemical screening uncovered the occurrence of flavonoids, steroids/triterpenes, cardiac glycosides, saponins, tannins, carbohydrates, and alkaloids in the crude methanol extract (CME), the ethyl acetate fraction (EAF), and butanol fraction. The maximum tolerated dose of the CME of did not produce observable signs of toxicity or death in all the rats given up to 500 mg/kg. The CME and EAF of fruits produced a significant ( ) reduction in the hatchability of eggs in a concentration-dependent manner, while the CME at concentrations between 12.5 and 100 mg/ml completely inhibited the hatching of eggs. Similarly, EAF at doses of 25, 50, and 100 mg/ml completely inhibited the hatching of eggs. The CME and EAF of fruits produced significant ( ) larvicidal activity against L of in a concentration-dependent manner while the CME at concentrations between 6.25 and 100 mg/ml caused larval mortality of L larvae completely. This study suggests that methanol extract and fractions of fruits possess beneficial anthelmintic (ovicidal and larvicidal) activity against , and may be a suitable alternative anthelmintic candidate for the control of nematodes.
蠕虫病是导致寄生虫病和动物生产力损失的主要原因之一。因此,控制蠕虫寄生虫至关重要。本研究旨在调查番荔枝科尖花藤果实对[具体寄生虫名称未给出]的体外驱虫活性。采用体外技术,对尖花藤果实提取物和馏分进行了杀卵(卵孵化抑制试验)和杀幼虫(幼虫死亡率试验)活性评估。此外,确定了成年白化大鼠给予尖花藤果实甲醇提取物(CME)馏分300、400和500mg/kg体重时的最大耐受剂量,并在48小时内观察毒性和死亡迹象。植物化学筛选发现粗甲醇提取物(CME)、乙酸乙酯馏分(EAF)和丁醇馏分中存在黄酮类、甾体/三萜类、强心苷、皂苷、单宁、碳水化合物和生物碱。给予高达500mg/kg的所有大鼠中,尖花藤果实CME的最大耐受剂量均未产生明显的毒性迹象或死亡。尖花藤果实的CME和EAF以浓度依赖性方式使[具体寄生虫名称未给出]卵的孵化率显著([具体显著程度未给出])降低,而浓度在12.5至100mg/ml之间的CME完全抑制了[具体寄生虫名称未给出]卵的孵化。同样,剂量为25、50和100mg/ml的EAF完全抑制了[具体寄生虫名称未给出]卵的孵化。尖花藤果实的CME和EAF以浓度依赖性方式对[具体寄生虫名称未给出]的[具体幼虫名称未给出]产生显著([具体显著程度未给出])杀幼虫活性,而浓度在6.25至100mg/ml之间的CME完全导致了[具体寄生虫名称未给出]幼虫的死亡。本研究表明,尖花藤果实的甲醇提取物和馏分对[具体寄生虫名称未给出]具有有益的驱虫(杀卵和杀幼虫)活性,可能是控制线虫的合适替代驱虫候选物。
