An equiproportional mixture of dihydroergocornine mesylate, dihydroergocristine mesylate, and ratio of dihydro-α-ergocryptine mesylate to dihydro-β-ergocryptine mesylate is (1.5-2.5:1) [8067-24-1]
» Ergoloid Mesylates is a mixture of the methanesulfonate salts of the three hydrogenated alkaloids, dihydroergocristine (C35H41N5O5·CH4O3S), dihydroergocornine (C31H41N5O5·CH4O3S), and dihydroergocryptine (C32H43N5O5·CH4O3S), in an approximate weight ratio of 1:1:1. Ergoloid Mesylates contains not less than 97.0 percent and not more than 103.0 percent of the alkaloid methanesulfonate mixture, calculated on the anhydrous basis, and not less than 30.3 percent and not more than 36.3 percent of the methanesulfonate salt of each of the individual alkaloids. Dihydroergocryptine mesylate exists as a mixture of alpha- and beta- isomers. The ratio of alpha- to beta- isomers is not less than 1.5:1.0 and not more than 2.5:1.0.
