P-Ergocryptine

A cmrently remaining problem in resolution is the occasional coelution of some ergot alkaloids, p-ergocryptine and ergocristine coelute under some conditions, leading to errors in the quantification of both when they are detected by FLD. LC-MS/MS methods can distinguish between these compounds as they have different molecular masses. The situation is less satisfactory for the isomers a- and p-ergocryptinine, which are not separated on LC and have identical masses, and so LC-MS cannot tell them apart. [Pg.4402]
