allocryptopine/papaver

Papaver degenii (Urum. & Jav.) Kuzmanov is a Bulgarian endemic and glacial relict growing in the alpine zone of Pirin Mountains and it is included in the Red Data Book of Bulgaria. Numerous plants were in vitro multiplied in order to study the alkaloid composition of the species and to test the

A new promorphinane alkaloid (-)-8,14-dihydroflavinantine was isolated from the aerial parts of Papaver nudicaule L. (Papaveraceae) growing in Mongolia. Six known isoquinoline alkaloids (+)-amuronine, pseudoprotopine, allocryptopine, (-)-dihydroamuronine, (-)-amurensinine N-oxide A and

Papaver nudicaule L. (Iceland poppy) is widely used for ornamental purposes. A previous study demonstrated the alleviation of lipopolysaccharide-induced inflammation mediated by P. nudicaule extract through nuclear factor-kappa B and signal transducer and activator of

Sanguinarine is a benzo[c]phenenthridine alkaloid with potent antimicrobial properties found commonly in plants of the Papaveraceae, including the roots of opium poppy (Papaver somniferum). Sanguinarine is formed from the central 1-benzylisoquinoline intermediate (S)-reticuline via the

The alkaloid pattern of the endemic plant Papaver coreanum Nakai (Papaveraceae) was determined for the first time. Eight alkaloids could be identified by LC/ESI-MS/MS and high-resolution mass spectrometry. Among them, protopine and allocryptopine represent the main components. Besides
