Résumé
BACKGROUND: Fourteen species of the genus Iris L is grown in Mongolia. Iris L has been in traditional Mongolia medicine for treatment of urinary and kidney disease. We investigated three species of Iris L such as Iris Bunge /Iris Bungei Maxim/, Iris Tigrida /Iris Tigrida Bge / and Iris lactea /Iris Lactea Pall/ which contains rich amount of biological active substances[1,2]. Urine was collected at tubes during 4 hours, since given experimental and standard preparations orally and compared with control group. As experimental results, the urine levels of treatments groups increased 1.13 fold (Iris Bunge), 1.8 fold (Iris Tigrida), 1.04 fold (Iris Lacteal) and 1.15 fold (Standard or Nefromon) compared with control groups. These results indicated the Iris Tigrida has shown diuretic effect more than other species of Iris L.\Z TOOLS AND METHODS: Adult Balb/c mice, each in the weight range of 20-28g, were obtained from the Vivarium, Drug research institute. The animals divided into five groups of four animals each and kept in cages and housed under standard conditions of temperature, humidity and dark light cycle (12h-12h). Diuretic activity was determined by the following methods of Trendelenburg et al (1980). Before experiment, all the animals received priming dose of 0.9% sodium chloride solution (0.3 ml/20g) and the treated groups were given 0.1ml/20g extracts of Iris L. The standard groups were given 0.1 ml/20g of “Nefromon. Immediately after respective treatments the animals were placed in metabolic cages and urine was collected in a measuring cylinder till 4 hours. RESULTS AND CONCLUSION: Results are shown in the ethanol extract of the whole plant of Iris Tigrida Bge at a dose of 0.1ml/20g observed diuresis during the 4 hours of the test (Tigrida Bge 1.0±0.37 ml versus control 0.55±009 ml, whereas in case of standard Nefromon the volume was found to be 0.63±0.08 ml, p<0.05). As experimental Iris L, results, urine levels of treatments groups increased 1.04 fold (Iris Bunge), 1.8 fold (Iris Tigrida), 1.05 fold (Iris Lacteal) and 1.15 fold (Standard or Nefromon) compared with control groups. These result, indicated the Iris Tigrida has shown diuretic effect more than other species of Iris L. These results indicated the Iris Tigrida has shown diuretic effect more than other species of Iris L. KEY WORDS: Diuretic, medicinal plants, Trendelenburg methods, flavonoids
