Toxicological Evaluation Of Calotropis Procera Against Freshwater Snails
Published 2011 · Biology
Calotropis procera, commonly known as “Arka,” is a popular medicinal plant found throughout the tropics of Asia and Africa. It has been widely used in the Indian traditional medical system for the treatment of a variety of disease conditions due to the presence of four ursane-type triterpenoids: cardiac glycosides, alkaloids, flavonoids, tannins and saponins. This study evaluated the toxicity of aqueous, ethanolic, and chloroform extracts of different parts of plant C. procera against two species of harmful snails: Lymnaea acuminata and Indoplanorbis exustus. The toxicity of these extracts were both time- and dose-dependent. Aqueous extracts of all parts of C. procera were less toxic compared to the ethanol and chloroform extracts. The chloroform extracts of all plant parts were more toxic than aqueous and ethanol extracts. Chloroform extracts of root and latex exhibited 4.27 and 4.88 96h LC50 against Lymnaea acuminata and Indoplanorbis exustus, respectively.
