The major alkaloids obtained from Papaver cylindricum Cullen were oripavine, narcotine, thebaine and rhoeadine. Floripavidine, papaverine, salutaridine, armepavine, N-methylasimilobine, scoulerine and cheilanthifoline were obtained as minor alkaloids. There have been no previous reports of alkaloids
The major alkaloids of PAPAVER TRINIIFOLIUM collected in two different parts of Anatolia have proved to be of the aporphine, morphinane and rhoeadine types. The two collections possessed different major alkaloids and the existence of chemical strains is indicated. In addition to the
Elicitors play an important role in challenging the plant defense system through plant-environment interaction and thus altering the secondary metabolite production. Culture filtrates of four endophytic fungi, namely, Chaetomium globosum, Aspergillus niveoglaucus, Paecilomyces lilacinus, and
Formation of the methylenedioxy bridge is an integral step in the biosynthesis of benzo[c]phenanthridine and protoberberine alkaloids in the Papaveraceae family of plants. This reaction in plants is catalyzed by cytochrome P450-dependent enzymes. Two cDNAs that encode cytochrome P450 enzymes
Macleaya cordata produces a variety of benzylisoquinoline alkaloids (BIAs), such as sanguinarine, protopine, and berberine, which are potential anticancer drugs and natural growth promoters. The genes encoding the berberine bridge enzyme (BBE) were isolated from M. cordata and Papaver somniferum,
