From Fumaria parviflora Lam. were isolated the major alkaloids protopine and adlumidiceine and the minor alkaloids parfumine, fumariline, dihydrofumariline, cryptopine, (-)-stylopine, 8-oxocoptisine, sanguinarine, and oxysanguinarine. The quaternary protoberberine fraction gave coptisine.
The isotachophoretic separation of some isoquinoline alkaloids in acid-base partially purified extracts from Bulgarian FUMARIA PARVIFLORA was studied. The electrolyte system for model mixtures of alkaloids (-)-stylopine, (-)-canadine, coptisine, berberine, protopine, cryptopine, chelidonine,
