An in vitro screening potential traditional medicinal plants for nephrolithiasis

Today, the attention of researchers has been drawn to the use of medicinal plant for the treatment of kidney stones. The aim of this study was to investigate the effect of five plants used in traditional medicine on the dissolution of calcium oxalate and calcium phosphate stones. Then, the ability of more effective plants to dissolve stones collected from patients after Percutaneous Nephrolithotripsy was investigated. The aerial part of plants were extracted by maceration method. The synthesized stones in laboratory were incubated with different concentrations of the extract. Next, the concentrations of calcium oxalate and calcium phosphate were measured by a calcium kit and BT 3000. The effect of the extract with the best activity on the stones collected from the patients was also studied. The composition of clinical stones was determined by colorimetric method. The total phenolic content (TPC) of the extracts was determined. The highest dissolution of calcium oxalate stones was observed by the G. struthium extract and the highest dissolution of calcium phosphate stones by the A. euchroma and A. officinalis root extracts. The dissolution percentage of clinical stones by the A. euchroma extract was significantly higher than other extract (P < 0.05). The highest TPC was observed in A. euchroma extract (P < 0.05). The A. euchroma extract exhibited the greatest dissolution activity on laboratory calcium oxalate and calcium phosphate stones as well as clinical stones made of high amounts of calcium oxalate. Therefore, the extract can be effective in preventing and treating kidney stones.
