The molluscicidal profile and brine-shrimp bio-activity of the ethanolic extracts of plants from the Bignoniaceae family were determined. The six extracts investigated were of the stems of Melloa quadrivalvis and Tabebuia aurea, and whole plants of Adenocalymma comosum, Arrabidaea parviflora, Cuspidaria argentea and Clytostoma binatum. When tested in the laboratory, with Biomphalaria glabrata as the test snail, all six extracts gave median lethal concentrations (9-54 microg/ml) that fell well below the upper threshold, of 100 mug/ml, set for a potential molluscicide by the World Health Organization.
测定了紫葳科植物乙醇提取物的杀螺活性和卤虫生物活性。所研究的六种提取物分别来自四瓣美洛花和金黄风铃木的茎，以及多花腺萼木、小花拟紫葳、银叶尖瓣藤和双齿炮仗花的全株。在实验室以光滑双脐螺作为试验螺进行测试时，所有六种提取物的半数致死浓度（9 - 54微克/毫升）均远低于世界卫生组织为潜在杀螺剂设定的100微克/毫升的上限阈值。
