ABSTRACT

Introduction: Solanum nigrum L. is used as antiseptic, expectorant, digestive,cardotonic diaphoretic and sedative agent. The leaves are used as poultice for rheumatism, skin diseases, and for the treatment of tuberculosis. It is considered a potent antiinflammatory.
Objectives: to determine the phytochemical screening of ethereal, alcoholic and watery extracts from the Solanum nigrum L leaves and stems.
Methods: steams and leaves were harvested, washed, disinfected, dried off, pulverized, and finally underwent consecutive extraction processes with growing polarity solvents. The extracts were filtered and subjected to phytochemical tests to identify the secondary metabolites.
Results: the results of the phytochemical study performed to ethereal, alcoholic, and watery extracts of leaves and stems, showed the existence of several families of secondary metabolites such as alkaloids, flavonoids, coumarins tannins, and saponins.
Conclusions: alkaloids, flavonoids, coumarins and tannins are significantly present; they arouse the pharmacological and biological interest because of their possible therapeutic applications.
