title: [Preliminary study on molluscicidal effect of active components from Centipeda minima].
abstract: The active components from Centipeda minima were extracted by water or ethanol, and identified by FTIR spectroscopy and UV-visible spectrophotometer. The molluscicidal effect of aqueous extract and ethanol extract from Centipeda minima against Oncomelania hupensis was determined as referring to the WHO guidelines for laboratory molluscicidal test. Treated with over 2.0 g/L aqueous extract and ethanol extract for five days, the mortality of O. hupensis was up to 100%, and their LC50, for snails was 0.50 g/L and 0.62 g/L, respectively. The molluscicidal activity of aqueous extract was higher than that of ethanol extract. The main components of aqueous extract and ethanol extract were sesquiterpenes lactones and sterols.
