RESUMEN
Objectives: The plant Kigelia africana (Lam.) Benth. Family: Bignoniaceae is used in traditional medical practices of Africa and India to treat various diseases including renal disorders. The present study is designed to evaluate the effect of K. africana fruit extract (KAFE) for in-vitro anti-urolithic activity on generated calcium-oxalate crystals. Method: The aqueous and alcoholic (ethanolic) extracts of fruits were tested for anti-urolithiatic potential on generated calcium-oxalate crystals by homogenous precipitation method and simultaneously a supporting two step vice-versa reactions were assessed (New method). The activity was assessed by studying the crystal dissolution by microscopy and quantitative alimental ions analysis for calcium and oxalates. Result: They exhibited significant activity when compared to standard drug Cystone- a poly herbal formulation. The aqueous and alcoholic extracts significantly decreased (p < 0.001) crystal size and increased calcium and oxalate concentration in reaction setup of all tested groups as compared to normal control. Simultaneously a supporting two step vice-versa reaction was assessed that have shown significant inhibition of crystal formation. Conclusion: All the interpretations of various result outcomes direct the use of this drug for urolithiasis prophylaxis and treatments.
