Effects of Heating, Pelleting, and Feed Matrix on Apparent Concentrations of Cereal Ergot Alkaloids in Relation to Growth Performance and Welfare Parameters of Backgrounding Beef Steers

open access: yesToxins, 2022
As the contamination of cereal grains with ergot has been increasing in Western Canada, studies were undertaken to evaluate the impacts of heating (60, 80, 120, or 190 °C) alone or in combination with pelleting on concentrations of ergot alkaloids ...

Cyclopropanation of carbon-carbon double bonds in ring d of ergot alkaloids [PDF]

open access: yes, 2013
Some ergot alkaloid derivatives containing a double bond in ring D have been reacted with diazomethane/palladium diacetate reagent to result in formation of a fused cyclopropane ring.

Impacts of cereal ergot in food animal production

open access: yesFrontiers in Veterinary Science, 2016
The negative impacts of ergot contamination of grain on the health of humans and animals were first documented during the 5th century AD. Although ergotism is now rare in humans, cleaning contaminated grain concentrates ergot bodies in screenings which ...

An integrated targeted and untargeted approach for the analysis of ergot alkaloids in cereals using UHPLC - hybrid quadrupole time-of-flight mass spectrometry [PDF]

open access: yes, 2015
An ultra-high performance liquid chromatography hybrid quadrupole time of flight (Q-TOF) mass spectrometry (MS) method is described for the simultaneous quantitative determination of common ergot alkaloids and the screening, detection and identification ...

The Usage of Ergot (Claviceps purpurea (fr.) Tul.) in Obstetrics and Gynecology: A Historical Perspective

open access: yesToxins, 2021
In the past centuries consumption of bread made of ergot-infected flour resulted in mass poisonings and miscarriages. The reason was the sclerotia of Claviceps purpurea (Fr.) Tul.—a source of noxious ergot alkaloids (ergotamine and ergovaline).

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

Ergot Alkaloids in Feed for Pekin Ducks: Toxic Effects, Metabolism and Carry Over into Edible Tissues

open access: yesToxins, 2015
Hardened sclerotia (ergots) of Claviceps purpurea contaminate cereal grains and contain toxic ergot alkaloids (EA). Information on EA toxicity in ducks is scarce.

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.

Novel Ergot Alkaloids Production from Penicillium citrinum Employing Response Surface Methodology Technique

open access: yesToxins, 2020
Ergot alkaloids are novel pharmaceutical and therapeutic agents synthesized in this study using fungal species Penicillium citrinum. To get the maximum yield of ergot alkaloids a statistical process of response surface methodology was employed using ...
