Abstract
U ovom je radu optimizirana i vrednovana metoda odreĎivanja glutationa slijednom analizom injektiranjem uz spektrofotometrijski detektor. Metoda se temelji na redoks-reakciji izmeĎu bakar(II)- neokuproin kompleksa i glutationa (GSH). Glutation ima ulogu reducensa te kao produkti nastaju oksidirani oblik glutationa (GSSG) i bakar(I)-neokuproin kompleks koji postiţe apsorpcijski maksimum pri λ = 458 nm. Optimizacijom parametara protočnog sustava obuhvaćeni su redoslijed injektiranja reagensa i uzorka, brzina protoka osnovne otopine, volumeni injektiranja analita i uzorka, duljina reakcijske uzvojnice te volumen petlje zadrţavanja. Tako optimiziranom metodom ostvareno je linerano dinamičko područje (LDP) u koncentracijskom rasponu od 6,00 × 10 ─7 mol L ─1 do 8,00 × 10 ─5 mol L ─1 uz pripadajuću jednadţbu pravca y = 3270 x – 0,0010 i koeficijent linearne regresije R 2 = 0,9983.Izmjerene su vrijednosti posluţile kao temelj za računanje granice dokazivanja (LOD = 2,20 × 10 ─7 mol L ─1 ) i granice odreĎivanja (LOQ = 6,00 × 10 ─7 mol L ─1 ). U odreĎivanju analita predloţenom metodom interferirali su: limunska kiselina, vinska kiselina, acetilsalicilna kiselina te natrijev citrat. Temeljem 15 uzastopnih injektiranja standardne otopine uzorka utvrĎena je ponovljivost metode uz relativno standardno odstupanje, RSD = 3,80 %. Mjerenjem smjesa otopina realnog uzorka i standardne otopine glutationa različitih koncentracija vrednovana je točnost metode. UsporeĎeni su rezultati odreĎivanja glutationa u realnom uzorku predloţenom metodom i metodom preporučenom farmakopejom. Slaganje rezultata (52,00 mg i 50,86 mg) upućuje na točnost metode.
Abstract (english)
A method for determination of glutathione using sequential injection analysis had been optimized and validated. The method is based on a redox reaction between glutathione and Cu(II)-neocuproine complex where glutathione is a reducens. Reaction products are oxidised form of glutathione (GSSG) and Cu(I)-neocuproine complex which reaches its absorption maximum at λ = 458 nm. Optimized parameters of flow system include sequence of injection of sample and reagent, rate of flow of carrier solution, volumes of injection of sample and reagent, volume of holding coil and lenght of reaction coil. Optimized method parameters were used to plot the callibration curve. The following equation had been determined: y = 3270 x – 0,0010. Linearity is achieved at analyte concentrations ranging from 6,00 × 10 ─7 mol L ─1 to 8,00 × 10 ─5 mol L ─1 . Limit of detection is LOD = 2,20 × 10 ─7 mol L ─1 while the limit of quantification is 6,00 × 10 ─7 mol L ─1 . Following compounds interfere: acetylsalicilyc acid, tartaric acid, citric acid and natrium citrate. Repeatability was confirmed based on results of 15 sequential injections of standard solution of glutathione. Relative standard deviation was 3,80 %. Method accuracy was validated by determining concentrations of mixed solutions composed of glutathione standard solution and glutathione real sample solution. Results of the developed method were compared with results of pharmacopoeial method. Similar results (52,00 g and 50,86 g) indicate method accuracy.
