Antibacterial and Insecticidal Activity of Crude Seed Extracts of Annona squamosa L.
Journal Title: International Journal of Pharmaceutical Science Invention - Year 2017, Vol 6, Issue 9
Abstract
The present investigation was conducted to evaluate the antibacterial and Insecticidal efficiency of traditional plant Annonas quamosa. Seeds extract of plant Annonas quamosa were prepared by methanol extraction method at the ratio of 1:1. To check the antibacterial activity of custard apple seeds by using agar well diffusion method against Staphylococcus aureus, ,E. coli, K. pneumoniae and B. subtilis. Methanolic extract of Annonas quamosa showed strong inhibitory effect against S.aureus as compare to the other three organisms. Larvae and adults of Aedes albopictus and Culex quinquefasciatus were collected from the breeding sites in coastal region of Mumbai. Tests of susceptibility for larvae and imaginal stage of mosquitoes were realized to determine mortality and LC50 of mosquitoes. Chemical identifications showed that these extracts contain alkaloids and flavonoids compounds that probably confer their biological insecticidal proprieties. On adult mosquitoes, significant insecticidal effects were observed with methanol extracts of seeds of Annonas quamosa. The seed extracts of plants may be used as a natural insecticide.
