Abstract
The alkaloidal composition in the two title taxa differs only quantitatively. Both contain amurine as the main alkaloid. P. nudicaule ssp. xanthopetalum contains muramine, protopine and alkaloid PN1 (probably identical with (±)-nudaurine (Ia)) as dominant alkaloids; further were isolated amurensine, epialpinine, cryptopine, mecambridine and alpinigenine. Allocryptopine, papaverrubines A, B, D and G, palmatine and coptisine were detected chromatographically. The quaternary alkaloid fraction afforded cis-N-methylstylopinium hydroxide (as the iodide II) which was isolated for the first time from P. nudicaule. In P. nudicaule ssp. album the alkaloid PN1, epialpinine, amurensine and muramine represented the dominant alkaloids, accompanied with mecambridine, protopine, cryptopine, allocryptopine and alpinigenine. Among the quaternary alkaloids N-methylstylopinium hydroxide was found.
