Kidney stones are 80% made up calcium crystals. It is the most common type of kidney stones that usually forms as calcium oxalate. In this study, Bauhinia purpurea was the plant used in determining antiurolithiatic activity. It was extracted using 95% ethanol by soxhlation and was prepared in different test solutions A (0.00108g/ml), B (0.00215g/ml) and C (0.00325g/ml). The phytochemical screening revealed the presence of alkaloids, saponins, tannins, flavonoids and phenols. Absorbance reading of the crystals involved the use of spectrophotometer at 620 nm for both nucleation and aggregation assays. The decrease in absorbance values showed the presence of antiurolithiatic activity. The test solution C (0.00325g/ml) exhibited the lowest average absorbance reading, and greatest percent inhibition for nucleation assay (38.57%) and aggregation assay (49.89%) among the test solutions.....
