Abstract
The present study analyses qualitative and quantitative phytochemical and evaluates the antioxidant properties of the methanolic extract of the leaves, bark, roots and stem of Bursera Simaruba. The preliminary phytochemical screening revealed strong presence of alkaloids and flavonoids in the bark and the leaves of the plant. The extracts also showed a moderate presence of tannins, phenols, terpenoids, and saponins. The stem did not show strong presence of the tested metabolites. Moderate amounts of terpenoids and alkaloids are observed, as well as weak presence of amino acids, anthraquinones and saponins. Roots show high amounts of cardiac glycosides, as well as moderate amounts of amino acids and terpenoids. Alkaloids are weakly present in roots. This study also showed the total content of flavonoids present in each part of the plant using a colorimetric method. The leaves have the highest total content of flavonoids (23.97±0.41 µg/100g of dried extract) compared to the rest of the plant. The flavonoids concentrations of the roots, stem and bark were 0.21±0.01, 4.90±0.21 and 1.07±0.05 µg/100g of dried extract, respectively. The amount of flavonoids in the leaves is six times higher than the stem. Future studies will isolate, purify and characterize the bioactive compounds responsible for the antioxidant activity in Bursera Simaruba.
