Tropane alkaloids (TAs) are natural plant toxins that pose a risk to animal and human health. Sensitive analytical methods are needed to ensure the safety of feed and food. A study found that scopolamine and atropine are commonly present in feed, with soybean meals being the most contaminated material.
Tropane alkaloids (TAs) are naturally occurring plant toxins. Due to the fact that TA-producing plants can enter the food chain, they pose a risk for animals and human health. Therefore, sensitive analytical methods need to be developed to provide an adequate safety of feed and food. The presented method is based on liquid chromatography-mass spectrometry detection and enables the determination of scopolamine and atropine in compound feeds at a low level of contamination. Limits of quantification for scopolamine and atropine were 0.92 and 0.93 mu g kg(-1), respectively. Scopolamine-D-3 and atropine-D-3 were used for quantification. The method was successfully validated and applied to the analysis of 42 feed samples. Among investigated feeds, 67% contained at least one of the monitored alkaloids. Soybean meals were the feed materials contaminated most often, also with the highest determined concentrations of TAs, which reached 147.9 mu g kg(-1).
