Calpurnia aurea extracts are used in southern Ethiopia to protect stock against ticks. Acetone, hexane and water leaf extracts of C. aurea collected in southern Ethiopia were tested for repellent/attractant and acaricidal properties on unfed adult Rhipicephalus pulchellus ticks. In contrast to many other plant species evaluated, C. aurea extracts did not have repellent properties, but rather had a slight attractant capacity. With 20% and 10% acetone extracts, all ticks were either killed or their mobility severely compromised after 1microl of extract was topically applied on the abdomen. At a 5% concentration, 85% of ticks were still affected. A 10% aqueous solution also had a marked effect. The results prove the efficacy of the traditional use of this extract and may lead to a product that can be used commercially to protect animals against tick infestation, under subsistence as well as industrialized conditions.
金叶锦香草提取物被用于埃塞俄比亚南部来保护牲畜免受蜱虫侵害。在埃塞俄比亚南部收集的金叶锦香草的丙酮、正己烷和水的叶提取物，被测试其对未吸血的成年钝缘蜱的驱避/引诱和杀蜱活性。与许多其他被评估的植物物种不同，金叶锦香草提取物没有驱避特性，而是具有轻微的吸引力。用 20%和 10%的丙酮提取物，在腹部涂抹 1 微升提取物后，所有蜱虫要么被杀死，要么其移动能力严重受损。在 5%的浓度下，85%的蜱虫仍受到影响。10%的水溶液也有显著效果。这些结果证明了这种提取物的传统用途的有效性，并可能导致一种可以在商业上用于保护动物免受蜱虫侵害的产品，无论是在自给自足的条件下还是在工业化条件下。
