Evaluation of the biological activity of the molluscicidal fraction of Solanum sisymbriifolium against non target organisms

The evaluation of the biocidal activity of the fruit of Solarium sisymbriifolium involving non target organisms such as aquatic insects, fish and snails lead to the isolation of the steroidal alkaloids, solamargine and beta-solamarine, from the active fractions. The fractions A3 and C, with biological activity against fish, snail and aquatic insect and larvae, are able to affect the good functioning of ecosystem found on alimentary chain. The fraction B seems to be less toxic to fish and aquatic insect and larvae. The fraction B could thus be used as molluscicide in the future. (C) 2010 Elsevier B.V. All rights reserved.
