A new 4,5-dioxoaporphine, named corydione, was isolated from the whole herb of Corydalis bulbosa (L.) Dc (Papaveraceae), together with dehydronantenine, (-)-stylopine, (+)-bicuculline, (-)-adlumidine, (+)-nantenine, (+)-bulbocapnine, protopine (-)-domesticine, (+)-corydine, predicentrine, oxonantenine, (+)-isoboldine and nandazurine. Glaucine and thaliporphine were detected by means of thin-layer chromatography. In addition, one minor alkaloid Cb-4, uncompletely identified, was described. The spectral data of corydione, predicentrine and nandazurine are given.

Alkaloid extracts from 12 plant species of the families Amaryllidaceae, Fumariacae and Papaveraceae were studied with respect to their acetylcholinesterase inhibitory activity and alkaloid patterns. Fifty-three alkaloids were identified by GC-MS, including known acetylcholinesterase (AChE) inhibitors such as galanthamine, epigalanthamine, sanguinine and epinorgalanthamine in extracts of Amaryllidaceae plants and protopine in extracts of Fumariaceae and Papaveraceae plants. The galanthamine-containing extracts of the amaryllidaceous plants were found to be the most active while the extract of Corydalis bulbosa was the most active among the extracts of the tested plants from the Fumariaceae and Papaveraceae plants.

Blood levels were as low as 0.

As a result of the reinvestigation of the alkaloid content of CORYDALIS BULBOSA (L.) DC. (Papaveraceae), growing in Bulgaria, a new 8,11-dioxoaporphine alkaloid, named bulbodione, together with dihydrosanguinarine, dehydroglaucine, (+/-)-sinactine, glaucinone and bicucullinine were isolated.
