Description
Summary:	This study shows the results of application liquid chromatography-tandem mass spectrometry (LC/MS/MS) for assay of the content of [alpha]-tocopherol and coenzyme Q10 in bee products of animal origin, i.e. royal jelly, beebread and drone homogenate. The biological matrix was removed using extraction with n-hexane. It was found that drone homogenate is a rich source of coenzyme Q10. It contains only 8±1µg/g of [alpha]-tocopherol and 20±2µg/g of coenzyme Q10. The contents of assayed compounds in royal jelly were 16±3 and 8±0.2µg/g of [alpha]-tocopherol and coenzyme Q10, respectively. Beebread appeared to be the richest of [alpha]-tocopherol. Its level was 80±30µg/g, while the level of coenzyme Q10 was only 11.5±0.3µg/g. Copyright © 2016 John Wiley & Sons, Ltd.
