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. Adlumidiceine, dihydrofumariline, 8-oxocoptisine, sanguinarine, and oxysanguinarine were found in F. parviflora for the first time. F. kralikii Jordan gave, besides the major alkaloids protopine, fumarophycine, and O-methylfumarophycine, the alkaloids adlumidiceine, berberine, coptisine, cryptopine, (-)-stylopine, and (-)-canadine. Only protopine and cryptopine have been isolated from F. kralikii earlier.
