Lisuride dihydrogen maleate

Fig 2 Reflectance scan of a chromatogram track with 90 ng of each substance per chromatogram zone 1 = lisuride dihydrogen maleate, 2 = methyseigide maleate, 3 = dihydroeigotamine mesylate, 4 = ergotamine tartrate. 

Lisuride dihydrogen maleate (h/Jj 30-35), methysergide maleate (h/ij 40-45), dihydroergotamine mesylate (hRf 45-50) and ergotamine tartrate (hRj 70-75) appeared as blue violet chromatogram zones on a yellow background. The detection limits — calculated for free base — were 3-4 ng substance per chromatogram zone.
