ABSTRACT
The phytochemical contents of the leaves of Jatropha tanjorensis (Hospital Too Far) was investigated, using standard analytical method. Concentration for each of the parameters were 87.57 ± 0.736% for saponins, 7.75 ± 0.071% for alkaloid, 5.247 ± 0.680% for flavonoids, 3.760 ± 0.435 mg/100g for Tannins and 3.1839 ± 0.316 for cyanogenic glycoside mg/100g respectively. The results reveals that the obtained values were lower compared with the maximum recommended dietary allowance standard in foods.
