Rumen flukes, parasites of the superfamily Paramphistomoidea, are found in cattle rumen. Heavy infections can cause symptoms such as diarrhea, weight loss, and poor body condition, resulting in a decrease in milk and meat production. This study compares the tegumental surface change of as a response to ethanolic extracts of flowers and black pepper seeds. Adult flukes were subjected to various concentrations of crude extracts, including 12.5, 25, 50, 100, and 200 μg/mL for 12, 18, and 24 h incubation. Scanning electron microscopy (SEM) exhibited that the ethanolic extracts of both flowers and black pepper seeds caused tegumental surface changes in adult . Based on the results, flower extract has anthelmintic activity, compared with black pepper seed extract, towards adult due to the deformation of the tegument at lower concentrations than black pepper extract.

木棉花和黑胡椒籽提取物引起的Paramphistomum epiclitum 皮层表面变化


瘤胃吸虫是Parampistomoidea总科的寄生虫，存在于牛瘤胃中。严重感染会引起腹泻、体重减轻、身体状况不佳等症状，导致产奶量和肉类产量减少。这项研究比较了花和黑胡椒种子乙醇提取物对皮膜表面的变化的反应。将成虫置于不同浓度的粗提物中，包括 12.5、25、50、100 和 200 μg/mL，孵育 12、18 和 24 小时。扫描电子显微镜（SEM）显示花和黑胡椒种子的乙醇提取物引起成虫的皮膜表面变化。根据结果​​，与黑胡椒种子提取物相比，花提取物对成虫具有驱虫活性，因为在比黑胡椒提取物浓度低的浓度下，其外皮变形。
