THE PRELIMINARY PHYTOCHEMICAL ANALYSIS OF NIGELLA SATIVA L. SMILAX ZEYLANICA L. & WITHANIA SOMNIFERA L. (DUNAL) PLANT PARTS.

Phytochemicals are plant-based chemicals with unique chemical, structural, and molecular properties. It is accepted that plant products are one of the major requirements of the world, from kitchens to laboratories plants are nature-gifted materials. This is because of plant chemicals. Plant-based chemicals play a crucial role throughout the world. So before using plants as our nutrition or medicine, it is mandatory to know their chemical content. The preliminary phytochemical analysis method allows us to understand the chemical content of plants or mixtures. In this study, two types of plant extracts were tested for phytochemical confirmation; phenol, alkaloid, flavonoid, tannin, saponin, glycoside & protein, 
some tests showed positive results in aqueous extracts, negative in methanol and some were positive for methanol & not in aqueous.
