Occurrence of Ergot Alkaloids in Barley and Wheat from Algeria [PDF]
Toxins, 2021 The natural occurrence of six major ergot alkaloids, ergometrine, ergosine, ergotamine, ergocornine, ergokryptine and ergocristine, as well as their corresponding epimers, were investigated in 60 cereal samples (barley and wheat) from Algeria. Ultra-high

Ergot Alkaloids on Cereals and Seeds: Analytical Methods, Occurrence, and Future Perspectives
Molecules, 2023 Ergot alkaloids are secondary metabolites resulting from fungi of the genus Claviceps that have proven to be highly toxic. These mycotoxins commonly infect cereal crops such as wheat, rye, barley, and oats.

Introduction to the Toxins Special Issue on Ergot Alkaloids [PDF]
Toxins, 2015 Ergot alkaloids are among the most relevant natural products in the history of toxins and pharmaceuticals. Until the late 20th century, human and livestock exposure to ergot alkaloids was primarily through ingestion of “ergots,” which are spur-shaped or ...

Genetics, Genomics and Evolution of Ergot Alkaloid Diversity [PDF]
Toxins, 2015 The ergot alkaloid biosynthesis system has become an excellent model to study evolutionary diversification of specialized (secondary) metabolites. This is a very diverse class of alkaloids with various neurotropic activities, produced by fungi in several

Methods of Lysergic Acid Synthesis—The Key Ergot Alkaloid
Molecules, 2022 Ergot is the spore form of the fungus Claviceps purpurea. Ergot alkaloids are indole compounds that are biosynthetically derived from L-tryptophan and represent the largest group of fungal nitrogen metabolites found in nature.

Vasoactive Effects of Acute Ergot Exposure in Sheep
Toxins, 2021 Ergotism is a common and increasing problem in Saskatchewan’s livestock. Chronic exposure to low concentrations of ergot alkaloids is known to cause severe arterial vasoconstriction and gangrene through the activation of adrenergic and serotonergic ...

The Impact of Storage Temperature and Time on Ergot Alkaloid Concentrations
Toxins, 2023 Ergot sclerotia produce toxic secondary metabolites, ergot alkaloids, that infect cereal crops and grasses. Ergot alkaloids have two isomeric configurations: the C-8-R-isomer (R-epimer), and the C-8-S-isomer (S-epimer).
