To assess the stability of the thiochrome derivatives, controls and patients samples (n = 25) were assayed immediately after potassium ferricyanide oxidation, then stored at 10[degrees]C in the dark and reassayed after 24 and 48 h.
Five milliliters of homogenates were mixed with 100 [micro]L of 0.04 M ammonium sulfamate, 200 [micro]L of 0.5 M lead acetate, and 2.5 mL of 20% (w/v) TCA and then made up to total volume of 10 mL with DW following incubation with 2 mL of 5 mM potassium ferricyanide in an ice under the dark for 60 min.
Potassium carbonate and potassium ferricyanide were used as a secondary oxidant in tert-butyl alcohol-water mixture (1: 1).
0.5 mL of each sample at different concentration (0.015-0.25 mg/mL in 70% ethanol) was mixed with 1.5 mL sodium phosphate buffer (pH 6.6, 0.2 M) and 1.5 mL 1% potassium ferricyanide solution.
We found that a strong CL signal was emitted when a trace amount of ENRO was added to luminol-potassium ferricyanide solution, and its intensity was strongly dependent on the ENRO concentration.
To 2.5 mL of rice extract (1.0 mg/mL), 2.5 mL of 2M sodium phosphate buffer (pH 6.6) and 5.0 mL of 1% potassium ferricyanide were sequentially added and mixed well.
They filled an electrochemical cell, essentially two glass jars joined with a glass tube, with an electrolyte solution of potassium ferricyanide and potassium chloride.
Each section was incubated (4 h in the dark at room temperature) in a microplate well filled with 3 ml of the following solution: acetylthiocholine iodide 2.5 mM, TMB, 0.1 M sodium citrate, 30 mM copper sulfate, and 5 mM potassium ferricyanide in distilled water.
Different spectrophotometric procedures have been reported for determination of PEH including the formation of ion-pair complexes between the drug and alizarine, alizarine red S, alizarine yellow G or quinalizarine [14], ninhydrin in sulfuric acid [15], nitrobenzene derivates in acetonitrile medium [16], oxidative coupling with 4-aminoantipyrine in the presence of potassium ferricyanide or sodium periodate [17,18], diazotized p-nitroaniline or 2-aminobenzothiazol in alkaline medium [19,20], forming a charge transfer complex with chloranil or haematoxylin in alkaline medium [21,22]= 7and[23].uranyl (II) ion forming a complex at pH.
The reducing power of the extracts was measured by incubating the reaction mixture (1 ml) containing the extract in phosphate buffer (0.2 mol/1, pH 6.6) with potassium ferricyanide (1 g/100 ml water) at 50[degrees]C for 20 min.
Stem bark extract (10-100 [micro]g) in 1 ml distilled water was mixed with 2.5 ml, 0.2 M, pH 6.6 phosphate buffer and 3 6 2.5 ml, 1 % Potassium Ferricyanide ([K.sub.3]Fe [(CN).sub.6), after which the mixture was incubated at 50[degrees]C for 20 minutes.
