Ergot alkaloids are indole metabolic compounds with specific biological activities (Schardl et al., 2006).
The present study was focused on the screening for the best fungal strain and the optimisation of culture conditions for enhanced production of ergot alkaloids using surface culture fermentation process.
Ergot alkaloids produced by the parasitic fungus Claviceps, which parasitises on cereals, include three major groups: clavine alkaloids, dlysergic acid (82) and its derivatives, and ergopeptines.
Despite a relatively low amount of agroclavine (7.20 [micro]g/kg) found in the samples, this is the first report in which a maize sample presented contamination by this ergot alkaloid. Agroclavine specifically modifies spatial memory in mice by impairing reproduction of conditioned navigation reflex in the Morris water test.

This lack of consistency is likely associated with the degree of stress on the animal and related to ambient temperature, concentration and type of ergot alkaloids present in the plant, the quantity of alkaloids in the animal's diet, and the physiology of the individual animal.
High doses of ergot alkaloids have been associated with toxicity in nursing infants.
Many of the ergot alkaloids are isomeric at the C-8 position [8-10], but none of these alkaloids is isomeric at C-5.
Some of the major classes of botanical and plant derived drugs are Tarpenes and Steroids, Glycosides, Ergot Alkaloids, Morphine Alkaloids and Vinca Alkaloids.
The Ergot Alkaloids were the very first anti-migraine-specific therapy class to reach the market.
Ergot alkaloids may lead to poor feathering and lesions forming on chickens, fescue foot in ruminants and shrunken udders in sows while endotoxins are responsible for endotoxic shock and death.
