Secondary metabolites from L. flowers extract exhibit anti-urolithiatic activity in adult Wistar albino rats.

The present study aims at evaluating potential of the ethanol extracts of leaves (LE), flowers (FlE) and roots (RE) in the treatment of renal calculi and characterising the secondary metabolites in the active extract. The results revealed that the FlE had significantly reduced the levels of kidney parameters (calcium, creatinine, urea, and uric acid) against ethylene glycol (EG) injuries, and restored the activity of glutathione peroxidase (GPx), superoxide dismutase and lipid peroxide malondialdehyde to the normal level. In addition, FlE significantly attenuated iNOS tissue expression caused by EG. The results obtained in this study suggest the potential value of the L. flowers as an antiurolithiatic agent.
