Determination of pyrrolizidine alkaloids in tea, herbal drugs and honey
Listed in DataCite
Honey was previously considered to be one of the main food sources of human pyrrolizidine alkaloid (PA) exposure in Europe.
Description
However, comprehensive analyses of honey and tea sampled in the Berlin retail market revealed unexpected high PA amounts in teas. Our study comprised the analysis of 87 honey as well as 274 tea samples including black, green, rooibos, melissa, peppermint, chamomile, fennel, nettle and mixed herbal tea or fruit tea.
Total PA concentrations in tea ranged from −1, while a mean value of about 10 µg kg −1 was found in honey samples. Additionally, herbal drugs were investigated to identify the source of PA in teas. Results suggest that PA in tea samples are most likely a contamination caused by co-harvesting of PA producing plants.

In some cases such as fennel, anise or melissa it cannot be excluded that these plants are able to produce PA themselves.
