Controlling species with plant products is crucial in the treatment of schistosomiasis since it is eco-friendly and generally less harmful to non-target organisms. The goal of this study was to determine the molluscicidal activity of an aqueous extract of leaves against A preliminary phytochemical screening test revealed the presence of flavonoids, terpenoids, steroids, anthraquinones, alkaloids, saponins, tannins, and carbohydrates. Following exposure to sub-lethal concentrations (LC 75.62 mg/L and LC 90.52 mg/L) of aqueous extract of , a reduction in survival, reproductive, and fecundity rates of were detected, as well as a substantial decrease in GSH, CAT, and SOD, while increasing MDA and NO levels. In addition, there was an increase in liver and renal functions as well as lipid profiles, compared to the control group. Histopathological examination of the digestive gland of treated showed a shrinkage of the tubules and an increase in the inter-tubular spaces as well as degeneration in the oocytes and spermatocytes of the hermaphrodite glands with a loss of connective tissues between the acini. Also, the comet assay revealed a genotoxic effect of aqueous extract of on with a significant increase in the tail moment, tail length, and DNA percentage reflecting DNA damage compared to the control group. Conclusively, aqueous extract acts as a natural molluscicidal agent against .
利用植物产品控制物种对于血吸虫病的治疗至关重要,因为它对生态环境友好,且通常对非目标生物危害较小。本研究的目的是测定叶片水提取物对的杀螺活性。初步的植物化学筛选试验表明,该提取物中存在黄酮类、萜类、甾体类、蒽醌类、生物碱类、皂苷类、单宁类和碳水化合物。在暴露于亚致死浓度(LC 75.62毫克/升和LC 90.52毫克/升)的水提取物后,检测到的存活率、繁殖率和生殖力下降,同时谷胱甘肽、过氧化氢酶和超氧化物歧化酶大幅减少,而丙二醛和一氧化氮水平增加。此外,与对照组相比,肝功能、肾功能以及血脂水平均有所升高。对经处理的消化腺进行组织病理学检查发现,小管萎缩,管间间隙增加,雌雄同体腺的卵母细胞和精母细胞退化,腺泡之间的结缔组织丧失。此外,彗星试验显示水提取物对具有遗传毒性作用,与对照组相比,尾矩、尾长和DNA百分比显著增加,反映出DNA损伤。总之,水提取物可作为一种天然的杀螺剂对抗。
