Ergovalide, also known as lysergylvaline amide or as N-lysergylvalylamide, is an ergot alkaloid of the lysergamide family found in Claviceps purpurea (ergot). It is said to constitute about 10 to 20% of the alkaloid content of ergot. However, according to a secondary source, ergovalide is probably a chemical artifact arising from solvolytic cleavage of ergocristine (lysergylvalylphenylalanylproline) (which is a highly variable constituent but can constitute as much as 50% of alkaloids in ergot). Ergovalide was first described in the scientific literature by A. N. Ban'kovskaya and colleagues in 1973.
