The molluscicidal activity of crude extracts from five highly potential plants, Annona squamosa seed, Nerium indicum Leaves, Stemona tuberose root, Cyperus rotundus corm and Derris elliptica root was assessed to Pomacea canaliculata. D. elliptica root and C. rotundus corm extracts showed the highest toxicity against 3-month old snails which have LC50 as 23.68 +/- 2.96 mg/l and 133.20 +/- 7.94 mg/l, respectively. The C. rotundus corm extracts were chosen for detoxification enzyme in vivo assay which shows esterase and glutathione S-transferase activity in stomach, intestinal tracts and digestive glands of survival treated P. canaliculata were inhibited.
对5种极具潜力的植物（番荔枝种子、夹竹桃叶、百部根、香附子球茎和鱼藤根）的粗提物针对福寿螺的杀螺活性进行了评估。鱼藤根和香附子球茎提取物对3月龄福寿螺显示出最高毒性，其半数致死浓度（LC50）分别为23.68±2.96毫克/升和133.20±7.94毫克/升。选择香附子球茎提取物进行体内解毒酶测定，结果显示，存活的经处理福寿螺的胃、肠道和消化腺中的酯酶和谷胱甘肽S-转移酶活性受到抑制。
