Ergot Alkaloids Produced by Endophytic Fungi of the Genus Epichloë
Toxins, 2015 The development of fungal endophytes of the genus Epichloë in grasses results in the production of different groups of alkaloids, whose mechanism and biological spectrum of toxicity can differ considerably.

Biosynthetic Pathways of Ergot Alkaloids
Toxins, 2014 Ergot alkaloids are nitrogen-containing natural products belonging to indole alkaloids. The best known producers are fungi of the phylum Ascomycota, e.g., Claviceps, Epichloë, Penicillium and Aspergillus species.

Monitoring and Managing of Ergot Alkaloids in Cereal Grains: A Comprehensive Analysis of Analytical Challenges, Sampling Uncertainty, and Processing for Food Safety. [PDF]
Compr Rev Food Sci Food SafABSTRACT Ergot alkaloids (EAs), toxic secondary metabolites produced by Claviceps purpurea, pose food and feed safety concerns for cereal grains, particularly rye and wheat. While EAs are most frequently associated with rye, their occurrence in other cereals has been increasingly reported across diverse regions.

UPDATED REVIEW ON EXTRACTION, ISOLATION AND QUANTITATIVE ESTIMATION OF ERGOT ALKALOIDS [PDF]
Bulletin of Pharmaceutical Sciences. Assiut University, 2022 Ergot Alkaloids are potent α-blockers that cause direct smooth muscle contraction. They are products of fungi in the genus Claviceps. The most prominent member of this group is Claviceps purpurea (rye ergot fungus).

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 ...
