Antilithiatic effect of C. dactylon, E. officinalis, K. pinnata, and B. nutans ethyl acetate fraction on glyoxylate-induced nephrolithiasis

Abstract

Abstract Background The plants Cynodon dactylon (C. dactylon), Emblica officinalis (E. officinalis), Kalanchoe pinnata (K. pinnata), and Bambusa nutans (B. nutans) have been reported to possess diuretic and antiurolithiatic potential against ethylene glycol and ammonium chloride along with in vitro calcium oxalate (CaOx) crystal growth inhibition property. Our previous research publications reported a rich presence of antioxidative phytocompounds like polyphenols and flavonoids in ethyl acetate fractions of these plants. This present study aims to explore antiurolithiatic potential of C. dactylon, E. officinalis, K. pinnata, and B. nutans ethyl acetate fraction following 7 days of sodium glyoxalate treatment on mice. Results Sodium glyoxylate treatment caused significant (P < 0.01–0.001) reduction in the urine magnesium and creatinine and elevation in oxalate, citrate, calcium, and phosphate levels. Ethyl acetate fraction of K. pinnata and B. nutans showed a highly significant antilithiatic effect by increasing urine volume, normalizing disrupted urine parameters, increasing LDH level, and decreasing kidney tissue oxalate content. E. officinalis and K. pinnata ethyl acetate fraction treatment showed a pronounced reversal of tubular dilation and damage of epithelial cell in kidney tissue with very less inflammatory cell infiltration. Conclusion The results signify the protective effect of K. pinnata and B. nutans ethyl acetate fraction rich with polyphenol and flavonoid on glyoxylate induced oxidative cell damage and morphological changes in mouse kidneys.
