lysergic acid/secale cereale

Ergot alkaloids are generally determined by high-performance liquid chromatography (HPLC) coupled to fluorescence detection (FLD) or mass selective detection, analyzing the individual compounds. However, fast and easy screening methods for the determination of the total ergot alkaloid content are

Analysis of ergot alkaloids remains a topic of importance and the European Food Safety Authority (EFSA) has encouraged laboratories to provide monitoring data for the further evaluation of their occurrence in food and feed. While LC-MS/MS has dominated developments in recent years, LC-FLD is still

The period 1940-80 in the history of ergot was dominated by two investigators, Arthur Stoll and Albert Hofmann. There was great excitement when their group isolated from ergot preparations the powerful psychotropic agent lysergic acid diethylamide (LSD). It was thought that this substance would help

The priority ergot alkaloids ergometrine and ergometrinine are highly toxic mycotoxins naturally occurring in different types of grains (i.e. rye, wheat, rice), as well as grain-based foods and, therefore, have gained increasing importance for food safety over the last years. The application of

Ergot alkaloids have an established place in plant pathology and toxicology. As pharmaceuticals, their sourcing is via natural or managed agricultural occurrence of sclerotia of Claviceps purpurea (Fr.) Tul. or through industrial fermentation processes with other Claviceps. The key

A case of severe limb ischaemia predominating in the legs in a young female drug addict is reported. Arteriography revealed diffuse spasm of all arteries of the lower limbs associated with localised spasm along the profunda artery in particular. These appearances regressed on control angiography

Six ergot alkaloids belonging to the lysergic acid derivatives (ergonovine (EGN) and methysergide hydrogen maleinate (MHM)) and peptide-type derivatives (ergocristine (EGR), ergotamine (EGT), ergocornine (EGC) and alpha-ergokryptine (EGK)) were studied by positive electrospray tandem mass

Ergot alkaloids produced by the fungus Claviceps parasitizing on cereals, include three major groups: clavine alkaloids, d-lysergic acid and its derivatives and ergopeptines. These alkaloids are important substances for the pharmatech industry, where they are used for production of anti-migraine
