Determination of Aflatoxin B1 Levels in Organic Spices and Herbs
Organically produced spices and herbs were analyzed for determination of aflatoxin B1 (AFB1) by ELISA using immunoaffinity column. For this purpose 93 organic spices and 37 organic herbs were randomly selected from organic markets and organic shops in Turkey. AFB1 was detected in 58 organic spice and 32 organic herb samples. Among organic spice samples, the maximum value was detected in cinnamo...
متن کاملThe determination of glutathione in the presence of nitrite.
Studies on the possible r&e of reduced glutathione (GSH) in the conversion of the drugs nitroglycerin and erythritol tetranitrate to nitrites (1) and in the reduction of methemoglobin to hemoglobin (2) have led to the need for a method of determining GSH in the presence of nitrite. The common methods for GSH cannot be employed for this purpose because nitrite interferes with the analyses. This ...
متن کاملDetermination of nitrite and nitrate in stored urine.
To the Editor: Nitric oxide (NOz) plays an important role both in maintaining normal homeostasis and in the pathogenesis of various disorders (1). NOz has a short biological half-life and is rapidly converted into its stable metabolites, nitrite and nitrate (1, 2). In plasma, nitrite is rapidly oxidized to nitrate (2). Determination of nitrite and nitrate (NOx) in body fluids like plasma and ur...
متن کاملSpectrophotometric determination of nitrite and nitrate using phosphomolybdenum blue complex.
A method for spectrophotometric determination of nitrite and nitrate is described. This method is based on the reduction of phosphomolybdic acid to phosphomolybdenum blue complex by sodium sulfide. The obtained phosphomolybdenum blue complex is oxidized by the addition of nitrite and this causes a reduction in intensity of the blue color. The absolute decrease in the absorbance of the blue colo...
متن کاملNitrite Determination by the Differential Pulse Polarographic Method
In this work; the optimum conditions of the differential pulse polarographic method conditions of the polarographic reduction of diphenylnitrosoamine which was occured by nitrite ion and diphenylamine in perchloric acidic medium and thiocyanate ion as catalyst, were determined. At these polarogram conditions, nitrite ion gave a maximum diffusion current at -0.56 V. The differential pulse polaro...
