The janthitrems: fluorescent tremorgenic toxins produced by Penicillium janthinellum isolates from ryegrass pastures

Abstract
New tremorgenic mycotoxins named janthitrem A, B, and C (molecular weights 601, 585, and 569, respectively) were produced by more than half of 21 Penicillium janthinellum isolates obtained from ryegrass pastures involved in ryegrass staggers outbreaks in sheep.
