Aptamer-based extraction of ergot alkaloids from ergot contaminated rye feed [PDF]

open access: yes, 2014
Ergot alkaloids are mycotoxins which can be found in food based on cereal-crops, due to a contamination of plants by fungi of the genus Claviceps. The ingestion of ergot contaminated cereal crops can lead to a severe poisoning known as ergotism. For food

Fate of Ergot Alkaloids during Laboratory Scale Durum Processing and Pasta Production

open access: yesToxins, 2019
The fate of ergot alkaloids during the milling of durum and subsequent production and cooking of pasta was examined. Durum samples containing varying amounts of ergot sclerotia (0.01–0.1% by mass) were milled, and all milling product was analyzed ...

Pd-catalyzed enantioselective aerobic oxidation of secondary alcohols: Applications to the total synthesis of alkaloids [PDF]

open access: yes, 2008
Enantioselective syntheses of the alkaloids (-)-aurantioclavine, (+)-amurensinine, (-)-lobeline, and (-)- and (+)-sedamine are described. The syntheses demonstrate the effectiveness of the Pd-catalyzed asymmetric oxidation of secondary alcohols in ...

Introduction to the Toxins Special Issue on Ergot Alkaloids

open access: yesToxins, 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 ...

Fungi - an Amalgam of Toxins and Antibiotics: a Mini- Review [PDF]

open access: yes, 2020
Fungi are eukaryotes with many functions. Earlier, fungi were classified in the plant kingdom but were later classified as a separate kingdom due to their unique cell walls. Fungi are heterotrophs like animals and are more closely related to animals. The

Ergot alkaloids contribute to virulence in an insect model of invasive aspergillosis

open access: yesScientific Reports, 2017
Neosartorya fumigata (Aspergillus fumigatus) is the most common cause of invasive aspergillosis, a frequently fatal lung disease primarily affecting immunocompromised individuals. This opportunistic fungal pathogen produces several classes of specialised

Metabolic pathway of oligosaccharides in sorghum honeydew caused by Claviceps africana Rota metabólica de oligossacarídeos em exsudato da "doença açucarada" do sorgo causado por Claviceps africana

open access: yesCiência Rural, 2008
The occurrence of the alditol oligosaccharides in the Claviceps afriana honeydew is partly as a rational expression of the pathogen's selective nutritive metabolism of the sucrose supplied by the host plant. The experiments were carried out in laboratory

Host specialization of different populations of ergot fungus (Claviceps purpurea)

open access: yesCzech Journal of Genetics and Plant Breeding, 2002
In our previous study of Claviceps purpurea three populations were found: G1 on open localities, G2 from shady or wet habitats and G3 on Spartina stands of coastal salt marshes. The latter two are also chemoraces.

Effects of Continuously Feeding Diets Containing Cereal Ergot Alkaloids on Nutrient Digestibility, Alkaloid Recovery in Feces, and Performance Traits of Ram Lambs

open access: yesToxins, 2017
Allowable limits for cereal ergot alkaloids in livestock feeds are being re-examined, and the objective of this study was to compare nutrient digestibility, growth performance and carcass characteristics of ram lambs fed a range of alkaloid ...

Occurrence of Ergot Alkaloids in Barley and Wheat from Algeria

open access: yesToxins, 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
