Analysis of phytochemical components and larvicidal activity of Thevetia peruviana (Pers) Merr, against the chickungunya vector Aedes aegypti (L)

Thevetia peruviana an evergreen shrub, belonging to Apocynanceae family, is a very poisonous shrub in nature and the kernels being the most toxic. This plant is native of central and South America, but now frequently grown throughout the tropical. The shrub or small tree that bears yellow or orange-yellow, trumpet like flowers and its fruit is deep red/black in color enhancing a large seed that bears some resemblance to a Chinese lucky nut . Leaves are covered in waxy coating to reduce water loss. The active principles in yellow oleander are cardiac glycosides. The physical properties of the fruit and kernel are unique and different from other tree borne oilseeds i.e. the storage, transport handling etc. Activities related to the fruits and kernels will require modifications in the processes and structures prevailing for other tree born oilseeds (Balusamy and Manrappan, 2007).
