Evaluation of mosquito Larvicidal potential against Culex quinquefasciatus and phytochemical profiling in Sesbania sesban Merr.
Venkatesh G, Arunprasath A
The aim of the present study was to investigate the Sesbania sesban plant for preliminary phytochemical screening, GC-MS analysis and Larvicidal activity against Culex quinquefasciatus. The presence of phytochemical compounds was screened by qualitative method. The results showed the presence of phytochemical compounds like alkaloids, steroids, glycosides, saponins, and tannins are present in petroleum ether and ethanol extracts. The flavonoids and phenols were present only in petroleum ether extract and absent in ethanolic extract. In GC-MS analysis there are three bio active phytochemical compounds were identified in ethanolic extract of S. sesban. The extract were subjected for screening of Larvicidal activity against Culex quinquefasciatus at the concentration of 2%, 4%, 8%, 10%, 15%, 20%, were analyzed the highest mortality was observed after 72hours in petroleum ether extract. But Low level of mortality was observed in ethanolic extract after 48hours.
