Phytochemical Investigation And Evaluation Of Larvicidal Property Of Leaf Extracts Of Hyptissuaveolens (L.) Poit Against Aedesaegypti (Linn.) (Diptera; Culicidae)
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2016, Vol 11, Issue 1
Abstract
A dried powdered leaf of Hyptissuaveolens was analyzed for its phytochemical constituents. The constituents present include carbohydrates, tannin, hydrogen cyanide, flavonoids, steroids, glycosides, terpenoids and alkaloids.The Larvicidal assay was carried out and graphs of percentage mortality of the three extracts were plotted. The LC50 values of chloroform, ethylacetate and ethanol extracts of Hyptissuaveolens against fourth instar larvae of Aedesaegyptis were 204.76, 45.57 and 282.89 respectively. Maximum larvicidal activity was observed in the ethyl acetate extract followed by chloroform and ethanol extract. No mortality was observed in the control. The ethyl acetate extract has the highest percentage mortality followed by the chloroform while the ethanol extract has the least activity according to WHO standard. The Larvicidal activity of most plants can be traced to the presence of these bioactive constituents.
