Phytochemical screening of Solanum nigrum L, S. myriacanthus Dunal, Solanum melongena and Averrhoa bilimbi in Bangladesh

Abstract

The main purpose of this study was to evaluate the phytochemical screening on leaf extract of Solanum nigrum L, S. myriacanthus Dunal, Solanum melongena and Averrhoa bilimbi which were from 3 districts in Bangladesh. Three districts were selected such as Khulna, Jessore and Satkhira. The phytochemical constituents like tannins, proteins, alkaloids, flavonoides and saponins of these species in dry and shady areas were investigated qualitatively. The results reveal that the proteins and alkaloids are more abundant on Solanum melongena and Solanum nigrum L respectively of shady areas. Tannins and Alkaloids are also abundant on S. myriacanthus Dunal of dry areas. Other phytochemical constituents such as saponins, flavonoides are more or less presence in these species of the study areas with proteins, alkaloids and tannins.
