Abstract

A rapid and sensitive liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS-MS) method for the determination of tridemorph and other pre- and post-harvest fungicides (carbendazim, thiabendazole, imazalil, propiconazole and bitertanol) in banana and orange samples has been developed and validated. The sample preparation was a simple extraction step with acetone using a high-speed blender prior to the injection of the five-fold diluted extract into the LC system with no other previous sample pre-treatment. Quantification was carried out using a matrix matched calibration curve which was linear in the range of 1-100 ng ml(-1) for all the compounds. The limit of quantification was 0.05 mg kg(-1) for all studied compounds, whereas limits of detection ranged between 0.005 and 0.025 mg kg(-1) (0.01 mg kg(-1) for tridemorph). Recoveries for tridemorph from spiked banana and orange samples at 0.05 and 1 mg kg(-1) were satisfactory, with values between 83 and 99% and relative standard deviations (R.S.D.s) lower than 13% (n = 5). For the other fungicides, recoveries between 75 and 95% with R.S.D.s lower than 12% were obtained. The developed method has been applied to the determination of selected fungicides in ...Continue Reading

Antifungals

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.
