Swainsonine content of New Mexican locoweeds

Swainsonine content of New Mexican locoweeds

Proceedings Western Section, American Society of Animal Science, July 8-10, 1992: Volume 43: 405-407

Locoweeds (Astragalus and Oxytropis spp.) vary widely in toxicity to livestock, which relates mainly to contents of the alkaloid swainsonine. In New Mexico, USA, 9 species of Astragalus and 2 of Oxytropis were collected and their methanol extracts were chromatographically analysed for swainsonine. Swainsonine concentrations in the foliage of locoweeds were from below 0.0005 to over 11.0 mg/g DM.
