Qualitative tests for alkaloids, saponins, tannins/polyphenols, steroids, tannins, anthraquinones, cyanogenic glycocides, and flavonoids were conducted. Further quantification of flavonoids using the Quercitin acid equivalence was employed in all extracts. Overall, alkaloids, flavonoids, saponins, steroids, tannins, and anthraquinones were found to be present in most of the extracts. The total flavonoids varied from 12.81 to 15.51mg/g in extracts. The maximum flavonoid content was found in the ethanolic bark extract (15.51mg/g) while the lowest flavonoid content was found in hexane leaf extract (12.81mg/g). Present findings were preliminary and further investigation is needed to determine the pharmacological applications of the plant. * Corresponding Author: Van Ryan Kristopher R.
