The evaluation of a new high-performance liquid chromatographic method is described. It permits the separation and determination of the four components of dihydroergotoxine (dihydroergocristine, dihydroergocornine, dihydro-alpha-ergocryptine, and dihydro-beta-ergocryptine) in a single step. On rever

✦ Synopsis
isomeric components glycerol 1,3-dioxan-5-01 acetonehexane as the Esterification chloride produces derivatives which are, however, completely resolved (R, > 2) by normal-phase silica; derivatization chromatography isolate each of the derivatives,, spectral properties. glycerol formal is calibrated standard in the direct determination
