| Abstract | ||
| The chemical components of the Urtica dioica L. leaves in the watery and alcoholic extracts were identified .The results showed that the extract contain : glycosides ,tannins ,phenolic compounds ,flavonoids ,alkaloids and proteins ,while the saponins and resins were not found. The results also showed that there were high concentrations of the following trace elements in the leaves K , Na , Fe with 12.5, 34 , 2.7 ppm, respectively and low concentrations of Ca , Zn with 10 , 8.2 ppm, respectively ,and Cu , Pb were not founds. The effects of these extracts on growth of different bacteria were studied, has been found that 0.5 mg/ml concentration was effective inhibitor of growth of Staphylocoous aureus , E.coli and Proteus mirabilis . The flavonoids were identified using high performance liquid chromatography (HPLC), as compared with standard .The results showed present of kaempferol, while morin was not found. | ||
