Extracts from the aerial parts of Solidago canadensis L. were evaluated for molluscicidal activity against Pomacea canaliculata Lam. using an immersion bioassay method. The petroleum ether fraction of the ethanolic extract (PEEE) from S. canadensis exhibited strong molluscicidal activity. The PEEE mode of action in the hepatopancreas tissue of P. canaliculata was tested at several concentrations. Biochemical parameters, namely, soluble sugar content, protein, malondialdehyde (MDA), acetylcholinesterase (AChE) activity, alanine aminotransferase (ALT), and aspartate transaminase (AST) were significantly decreased or increased after exposure to PEEE for 48 h (p<0.05). Histological assessment results showed that hepatopancreas tissue structure was destroyed by exposure to PEEE. Gas chromatography-mass spectrometry analysis (GC-MS) was used to identify 15 compounds that could contribute to the molluscicidal efficacy of the PEEE. Molluscicidal assay, biochemical tests and histological assessments suggest that the PEEE from S. canadensis has potential utility as a molluscicide.
从加拿大一枝黄花的地上部分提取的物质，采用浸渍生物测定法，对福寿螺进行了杀螺活性评价。加拿大一枝黄花乙醇提取物的石油醚部分（PEEE）表现出很强的杀螺活性。在几个浓度下，测试了 PEEE 在福寿螺肝胰腺组织中的作用模式。暴露于 PEEE 48 小时后，生化参数（可溶性糖含量、蛋白质、丙二醛（MDA）、乙酰胆碱酯酶（AChE）活性、丙氨酸氨基转移酶（ALT）和天冬氨酸氨基转移酶（AST））显著降低或升高（p<0.05）。组织学评估结果表明，肝胰腺组织结构因暴露于 PEEE 而被破坏。采用气相色谱-质谱分析（GC-MS）鉴定了 15 种可能有助于 PEEE 杀螺功效的化合物。杀螺试验、生化试验和组织学评估表明，加拿大一枝黄花的 PEEE 具有作为杀螺剂的应用潜力。
