Molecular Network-Guided Alkaloid Profiling of Aerial Parts of Papaver nudicaule L. Using LC-HRMS.[Pubmed:32517053]
Molecules. 2020 Jun 5;25(11). pii: molecules25112636.
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 transcription 3 inactivation. As isoquinoline alkaloids are chemical markers and bioactive constituents of Papaver species, the present study investigated the alkaloid profile of aerial parts of five P. nudicaule cultivars with different flower colors and a P. rhoeas cropped for two years. A combination of liquid chromatography high-resolution mass spectrometry and molecular networking was used to cluster isoquinoline alkaloids in the species and highlight the possible metabolites. Aside from the 12 compounds, including rotundine, Muramine, and allocryptopine, identified from Global Natural Products Social library and reported information, 46 structurally related metabolites were quantitatively investigated. Forty-two and 16 compounds were proposed for chemical profiles of P. nudicaule and P. rhoeas, respectively. Some species-specific metabolites showed similar fragmentation patterns. The alkaloid abundance of P. nudicaule differed depending on the flower color, and the possible chemical markers were proposed. These results show that molecular networking-guided dereplication allows investigation of unidentified metabolites. The derived chemical profile may facilitate evaluation of P. nudicaule quality for pharmacological applications.
Alkaloids from Corydalis decumbens suppress neuronal excitability in primary cultures of mouse neocortical neurons.[Pubmed:29571149]
Phytochemistry. 2018 Jun;150:85-92.
Eight previously undescribed alkaloids, named corydemine, dihydrocorydemine, corydedine, 8,13-dioxo-14-hydroxytetrahydropalmatine, egenine-alpha-N-oxide, egenine-beta-N-oxide, 7'-O-ethylegenine-alpha-N-oxide, and 7'-O-ethylegenine-beta-N-oxide, together with three known ones, Muramine, l-tetrahydropalmatine, and (+)-egenine, were isolated from the bulbs of Corydalis decumbens. Their structures were elucidated by comprehensive spectroscopic analysis and chemical correlation. The isolated compounds were tested for their ability to modulate neuronal excitability in primary cultured neocortical neurons. Four of the compounds, corydemine, dihydrocorydemine, Muramine, and l-tetrahydropalmatine, inhibited neuronal excitability with IC50 values of 3.6, 16.7, 13.5 and 14.0muM, respectively.
Alkaloids of papaver genus IX. Alkaloids of Glaucium vitellinum Boiss and Buhse, population Seerjan and Glaucium pulchrum Stapf, population Elika.[Pubmed:19671]
Lloydia. 1977 Jul-Aug;40(4):352-5.
Glaucium vitellinum Boiss and Buhse. population Seerjan was shown to contain three major alkaloids, isocorydine (0.44%), protopine (0.42%), dicentrine (0.24%), and four minor alkaloids, tetrahydropalmatine (0.13%), Muramine (0.12%), bulbocapnine (0.06%) and glaucine (0.01%). Glaucium pulchrum Stapf popllation Elika was shown to contain two major alkaloids, corydine (0.3%) and bulbocapnine (0.18%) and three minor alkaloids N-methylindcarpine (0.1%), isocorydine (0.03%) and protopine (0.01%). N-methyllindcarpine was found for the first time in the Papaveraceae and tetrahydropalmatine was detected for the first time in Glaucium.
