Abstract
The annual incidence of urolithiasis in industrialized regions is considered to be 1,500-2,000 cases per millions with reoccurrence rate of 75% in 20 years. There is no effective management therapy for renal calculi. Allopathic and herbal therapies havetheir inherent limitations and side-effects. Bergenia ligulata has been used since ancient time in many herbal compositions and it is major component of Cystone? (Himalaya, herbal healthcare) for treating kidney stones. The present work has been designed to study the anti-lithiatic potential of B. ligulata, isolation of the potent metabolite(s) and its mechanism of action. Commercially available dried rhizomes of B. ligulata were powdered and subjected to activity guided fractionation using in vitro calcium oxalate crystal growth inhibition assay. Further, rat hyperoxaluric model was used to assess anti-lithiatic ability in vivo. The isolated fractions showed anti-calcifying activity in vitro. The sequential isolation of the potent fraction led to the purification of the most active molecule. The metabolite was eventually characterized as bergenin employing LC-MS, NMR, FTIR and UV spectroscopy. Bergenin was found to be effective in reducing oxidative stressmarkers like malondialdehyde (187% in diseased vs. 20% in treated) and elevating reduced glutathione levels (-46% in diseased vs. -15% in treated). It exhibited anti-lithiatic activityas assessed by measuring the activity of lactate dehydrogenase and alkaline phosphatase in serum samples. The creatinine clearance was also normalized with bergenin treatment in rat hyperoxaluric model. The present study provides significant evidence in the effectiveness of bergenin in treating and managing renal calculi.
