Датум издавања: | 1-сеп-2011 | Издавач: | Taylor & Francis Group | Часопис: | Food Additives and Contaminants - Part A Chemistry, Analysis, Control, Exposure and Risk Assessment | Сажетак: | A new, rapid and sensitive multiresidue method is reported for the simultaneous determination of tropane alkaloids (tropine, atropine, scopolamine, homatropine, anisodamine) and glycoalkaloids (α-solanine,α-chaconine) in grains and seeds (wheat, rye, maize, soybean, linseed). Dispersive solid phase extraction (DSPE) was performed with 0.5% formic acid in acetonitrile/water and a mixture of magnesium sulphate, sodium chloride and sodium citrate. For a fast and effective clean-up procedure for oily matrices such as soybean and linseed, matrix solid phase dispersion (MSPD) C 18 material was used to remove co-extracted non-polar components. No clean-up was necessary for less oily matrices following extraction. The analytes were separated by isocratic HPLC on a Chirobiotic V column and detected using a triple quadrupole mass spectrometer with electrospray ionization (ESI). All analytes were monitored in the positive ion mode. The method performance is presented in terms of linearity in the range 5-80 ng/g (r 2 = 0.998), specifity, selectivity, accuracy (recoveries from 61-111%), precision (CV < 5%) and ruggedness. The limits of quantitation (LOQ) were in the range 2.2-4.9 ng/g. © 2011 Taylor & Francis. | URI: | https://open.uns.ac.rs/handle/123456789/10657 | ISSN: | 19440049 | DOI: | 10.1080/19440049.2011.584908 |
