Introduction: Cassia uniflora Mill is used for the allelochemical control of Parthenium hysterophorus; and its larvicidal activity on Aedes aegypti has been reported. It has also been applied as antispasmodic agent and as treatment of cutaneous rash. Objective: to perform a phytochemical screening on alcoholic, ethereal and aqueous extracts from the Cassia uniflora Mill species to identify the secondary metabolites of biological interest in therapeutics. Methods: aerial and underground parts of the plant were harvested, washed, disinfected, dried, powdered and subjected to successive extractions with solvents of increasing polarity. The extracts were filtered to carry out phytochemical tests for identification. Results: the phytochemical screening of ethereal, alcoholic and aqueous extracts from leaves, stems, fruit peels, seeds and roots, confirmed the existence of several families of secondary metabolites of biological and pharmacological interest such as quinones and coumarins that stand out because of their significance presence. Conclusions: according to the diversity of secondary metabolites in the tested parts of Cassia uniflora Mill, as well as the biological effects reported for this species, it would be interesting to conduct new studies to find pieces of evidence on its effectiveness and safety, as a way of supporting traditional use of this plant.
