In recent years, emphasis has been placed on the use of natural materials in the control and treatment of various infections, as some chemically synthesized drugs have undesirable side effects. Beech  forests  play  an  important  role  in  temperate in Golband area northern of Iran  since  they  occupy  infertile  montane  soils.Solid phase extraction of insignificant amounts of Phenols in Walnut (Juglans regia)  in aqueous samples using carbon nanotubes and visible and ultraviolet spectrophotometry measurement in biologic samples is used in his study. These systems include two phases, aqueous donor phase and conjugated carbon nanotube acceptor phase. Experiments were performed in two steps, aqueous phase extraction and of Phenols in Walnut (Juglans regia)  resorption using methanol acidic solvent and resorbed samples were provided to Vis-UV spectrophotometry for further analysis. This method is cheap, simple, fast, and compatible with most of instrumental analysis methods. Extraction parameters including resorbing organic solvent effect, pH of donor and acceptor phases, extraction duration, resorption duration, shaking time, volume of donor phases and surfactant effect were optimized and analysis and measurements were performed under optimized situation. Mentioned techniques had many advantages including; short extraction time, low consumption of organic solvents, removing the effect of prior experiments, low diagnosis threshold and high concentration factor. Concentration factor and diagnosis threshold were to be 51 and 9.51 for Phenols in Walnut (Juglans regia) . Linear domain and relative standard was 1.1153%.
