Collect. Czech. Chem. Commun. 1984, 49(5), 1318-1324. | Additional alkaloids from Glaucium squamigerum KAR. et KIR.[Reference: WebLink] | METHODS AND RESULTS:
A new quaternary alkaloid, (-)-β-N-methylisocorypalminium hydroxide, was isolated from KAR. et KIR. in the form of iodide. In addition to the already known to occur in this plant, allocryptopine (the main alkaloid), protopine, chelerythrine, sanguinarine, corydine, coptisine and berberine, additional , (-)-Chelidonine, (±)-chelidonine (diphylline) and chelirubine were also isolated from the non-quaternary fraction, while from the fraction of quaternary (-)-β-N-methylcanadinium iodide (the second main alkaloid), (-)-α-N-methylcanadinium iodide and (-)-β-N-methylstylopinium iodide were isolated after conversion of the to iodides. Further the presence of small amounts of stylopine, canadine, scoulerine, corysamine, corytuberine, magnoflorine, α-N-methylstylopinium hydroxide and β-N-methyltetrahydropalmatinium hydroxide were also detected. |
