In this work, we have studied the molluscicidal activity of different extracts obtained from Cotula cinerea and Quercus lusitania var. infectoria galls. The hydroalcoholic extract of Cotula cinerea, acetonic extract and gallotanin of Quercus infectoria galls have presented high activity against Bulinus truncatus. The hydroalcoholic extract of Cotula cinerea was fractionated by chromatography on silica gel column. We have isolated two very active fractions at concentrations respectively of 52.5 and 27.5 ppm.
在本研究中，我们研究了从灰香丝草和没食子中提取的不同提取物的杀螺活性。灰香丝草的水醇提取物、丙酮提取物以及没食子的没食子单宁对截形小泡螺均表现出高活性。灰香丝草的水醇提取物通过硅胶柱色谱进行分离。我们分别分离出了两种活性很强的馏分，浓度分别为52.5 ppm和27.5 ppm。
