Analysis of EU priority polycyclic aromatic hydrocarbons in food supplements using high performance liquid chromatography coupled to an ultraviolet, diode array or fluorescence detector
[en] High performance liquid chromatography coupled to an ultraviolet, diode array or fluorescence detector
(HPLC/UV-FLD) has been used to set up a method to detect the 15(+1) EU priority polycyclic aromatic
hydrocarbons (PAHs) in food supplements covering the categories of dried plants and plant extracts
excluding oily products. A mini validation was performed and the following parameters have been determined:
limit of detection, limit of quantification, precision, recovery and linearity. They were in close
agreement with quality criteria described in the Commission Regulation (EC) No 333/2007 concerning
the PAH benzo[a]pyrene in foodstuffs, except the not fluorescent cyclopenta[c,d]pyrene for which the UV
detection leads to a higher limit of detection. Analysis of twenty commercial food supplements covering
mainly the class of dried plants was performed to evaluate their PAHs contamination levels and to
test the applicability of the method to various plant matrices. Fifty percent of analyzed samples showed
concentration exceeding 2 gkg−1 for one or more PAHs.
