The present study was done to evaluate the antiurolithiatic activity of ethanolic extract of roots (ELC 200 mg/kg) and oleanolic acid (OA 60 mg/kg, O.A. 80 mg/kg, O.A. 100 mg/kg) isolated from roots of Lantana camara in albino wistar male rats using zinc disc implantation induced urolithiatic model. The group in which only zinc disc was implanted without any treatment showed increase in calcium output (23  ± 2.7 mg/dL). Cystone receiving animals showed significant protection from such change (P < 0.01). Treatment with OA and ELC significantly reduced the calcium output at a dose of OA 60 mg/kg (P < 0.01), OA 80 mg/kg (P < 0.01), ELC 200 mg/kg (P < 0.01), and OA 100 mg/kg (P < 0.001), as compared with zinc disc implanted group. The average weight of zinc discs along with the deposited crystals in the only disc implanted group was found to be 111 ± 8.6 mg. Group that received Cystone 500 mg/kg showed significant reduction in the depositions (P < 0.001). Similarly, the rats which received OA and ELC showed reduced formation of depositions around the zinc disc (P < 0.001). The X-ray images of rats also showed significant effect of OA and ELC on urolitiasis. Thus, OA and ELC showed promising antiurolithiatic activity in dose dependant manner.

S u m m a r yUrolithiasis is the process of formation of stone in the urinary tract by crystal nucleation, aggregation and retention in the urinary tract. Traditional medicinal plants have been successfully used to overcome urolithiasis. Hence, herbal formulation containing a mixture of plant extracts was prepared and evaluated for the antiurolithiatic activity. This formulation contained alcoholic extracts of fruit of Tribulus terrestris, root of Boerhavia diffusa and leaves of Azadirachta indica . Studies were performed in ethylene glycol-induced urolithiasis model using Cystone as a standard drug. Ethylene glycol increases the level of calcium, oxalate and phosphate which are responsible for urolithiasis. The herbal suspension decreased the level of calcium, oxalate and phosphate significantly at doses of 200 and 300 mg/kg when compared to the negative control group. Creatine, uric acid and urea were also decreased significantly at all dose levels. Histopathology has supported these results. The level of LD 50 was found to be higher than 2000 mg/kg. Therefore, the prepared formulation has appreciable significant antiurolithiatic activity and is safe for use.

The aim of the work is to perform the pharmacognostic study of the leaves of plant Triticum aestivum Linn., Family Poaceae, commonly known as ‘Wheatgrass’. It is cultivated on large scale all over India and also occasionally cultivated in garden. For the present study samples of the Wheatgrass leaves were collected over a specific period of nine days. The drug was cultivated with specific type of hybrid seeds obtained from most reputed institution of India and were scrupulously analysed. For standardization of the herbal drug morphological, phytochemical, physicochemical and microscopical examination was done. The leaves grown were found to be lax, cauline, flat, 0.6 to 0.25 inches (4 to 6 mm) wide, 6-9 inches long and green in color. The chemical compositions of the leaves are proteins, flavonoids, alkaloids, glycosides, terpenoides, saponins, fibers, tannins and phenolic compounds. The specific variety of seeds, specific time of collection made it more specific to be used for further pharmacological studies.DOI: http://dx.doi.org/10.3329/icpj.v3i6.18760 International Current Pharmaceutical Journal, May 2014, 3(6): 280-285
