Ergocryptine is an ergopeptine and one of the ergot alkaloids. It is isolated from ergot or fermentation broth and it serves as starting material for the production of bromocriptine.^[1]

Chemistry

Ergocryptine is a mixture of two very similar compounds, alpha- and beta-ergocryptine.^[2] The beta differs from the alpha form only in the position of a single methyl group, which is a consequence of the biosynthesis in which the proteinogenic amino acid leucine is replaced by isoleucine.
