Aminorex identified in horse urine following consumption of Barbarea vulgaris; a preliminary report

ConclusionsAminorex has been identified in post administration urine samples from horses fed freshly harvested flowering KentuckyBarbarea vulgaris, colloquially “Yellow Rocket”. These identifications are consistent with occasional low concentration identifications of Aminorex in equine samples submitted for drug testing. The source of these Aminorex identifications is believed to be the chemically related Barbarin, found as its precursor GlucoBarbarin i n KentuckyBarbarea vulgaris and related Brassicaceae plants worldwide.
