a fast and simple modified quechers extraction method was developed for determination of benzo[a]pyrene (bap) in 137 traditional (sangak), semi-industrial (sangak) and industrial bread samples using spiked calibration curves by gc/ms. sample preparation includes extraction of bap into acetone followed by cleanup with dispersive solid phase extraction. the limit of detection and limit of quantif...

Abstract Background Honeybees provide a wealth of valuable natural products containing health-promoting bioactive compounds, including honey, bee bread, venom, pollen, propolis, and royal jelly. In the present study, we investigated chemical composition four honeybee (bees, jelly, bread) derived from three medicinal plants (marjoram, trifolium, citrus) using headspace GC-MS.
