This study dealt with the phytochemical and vitamin constituents of Sennaoccidentalis (Uzakimma). The qualitative analysis of the plant indicated the presence of high presence of flavonoids, glycosides, alkaloids, terpenoids and, moderate presence of tannins, saponin, steroids, and phenol. The quantitative results were tannins 1.4775 ± 0.0495 mg/g, alkaloids 2.2280 ± 0.0283 mg/g, saponin 1.5830 ± 0.0141 mg/g, glycosides 2.1295 ± 0.1909 mg/g, terpenoids 2.7560 ± 0.1414 mg/g, flavonoids 2.1755 ± 0.0212 mg/g, steroids 1.1030 ± 0.1273 mg/g, phenol 1.3290 ± 0.0283 mg/g. The results of vitamin contents were vitamin A (0.6545 ± 0.0778 mg/g), vitamin B (1.5600 ± 0.0283 mg/g), vitamin B1 (0.8145 ± 0.9405 mg/g), vitamin B2 (0.2325±0.1202 mg/g), vitamin B3 (0.1200 ± 0.0566 mg/g), vitamin B6 (0.2390 ± 0.0283 mg/g), vitamin B9 (1.2280 ± 0.3536 mg/g), vitamin C (1.0610 ± 0.8061 mg/g), vitamin D (0.3430 ± 0.1273 mg/g), vitamin E (0.5285 ± 0.0212 mg/g) and vitamin K (0.6170 ± 0.000 mg/g). The result indicates that there are phytochemicals and vitamins in Uzakimma that could be useful in medicine.
