TL;DR: Two competitive inhibition enzyme-linked immunosorbent assays for riddelliine, riddellii N-oxide, and other closely related pyrrolizidine alkaloids were developed using polyclonal antibodies and suggest that these techniques will be excellent tools to diagnose poisoned animals and identify highly toxic plants.

TL;DR: Differences in concentrations of tremetone, dehydrot Remetone, and 3-oxyangeloyl-tremetone in white snakeroot and rayless goldenrod plants may explain the historical sporadic and unpredictable toxicity of these plants to livestock and humans.

TL;DR: This is the first detailed MS analysis of known indole diterpenes and possible isomers in I. asarifolia and I. muelleri and provides valuable information for indoles diterpene characterization.

TL;DR: Forty of the fifty-three swainsonine-positive taxa had not been determined to contain swains onine previously using liquid or gas chromatography coupled with mass spectrometry and will serve as a reference for risk assessment and diagnostic purposes.

TL;DR: In this paper, the authors present examples of plants poisonous to animals and include the steroidal alkaloid toxin of Veratrum californicum (Western false hellebore), piperidine alkaloids of Lupinus species (lupines), and polyhydroxy indolizidine, pyrrolizidine and nortropane alkalids of Astragalus and Oxytropis species (locoweeds), Castanospermum australe (Moreton Bay chestnut) and Ipomoea species (morning glories).
