dihydrosanguinarine/キケマン属

From the whole plant of Corydalis thyrsiflora Prain, an herbal medicine used in Tibet, 12 isoquinoline alkaloids were isolated and identified as protopine, dl-tetrahydrocoptisine, l-sinactine, l-cavidine, d-bicuculline, d-corlumine, sibiricine, ochotensine, dihydrosanguinarine,

OBJECTIVE To study the alkaloid component of Corydalis adunca Maxim. METHODS The constituents were isolated by chromatographic methods, their structures were elucidated by spectroscopic evidences. RESULTS Three compounds were purified and their structures were identified, they were identified as

OBJECTIVE To study the alkaloid constituents of Corydalis adunca. METHODS The constituents were isolated on silica gel column and their structures were elucidated by IR, NMR, MS data. RESULTS Eight alkaloid compounds were isolated from alcohol extracts of the herb of C. adunca, and identified as

Four new alkaloids, characterized as 6-(2-hydroxyethyl)-5,6-dihydrosanguinarine (1), 6-acetonyl-5,6-dihydrosanguinarine (2), N-methyl-2,3,7,8-tetramethoxy-5,6-dihydrobenzophenanthridine-6-ethanoic acid (3), N-methyl-2,3,7,8-tetramethoxy-6-oxo-5,6-dihydrobenzophenanthridine (4), together with

From the herbs of CORYDALIS BUNGEANA, 16 alkaloids were isolated; 3 of them were identical with acetylcorynoline ( 2), corynoline ( 5), protopine ( 9), which had been obtained before from this plant. A further 11 known alkaloids: dihydrosanguinarine ( 1), acetylisocorynoline ( 3), 11-epicorynoline (

As a result of the reinvestigation of the alkaloid content of CORYDALIS BULBOSA (L.) DC. (Papaveraceae), growing in Bulgaria, a new 8,11-dioxoaporphine alkaloid, named bulbodione, together with dihydrosanguinarine, dehydroglaucine, (+/-)-sinactine, glaucinone and bicucullinine were isolated. These

Six tetrahydroprotoberberines, (+)-sinactine, apocavidine, stylopine, (+)-cavidine, cheilanthifoline, and dehydrocavidine; two spirobenzylisoquinolines, yenhusomine and yenhusomidine; one phthalideisoquinoline, corlumine; one benzophenanthridine, dihydrosanguinarine and protopine, have been isolated

Six tetrahydroprotoberberines, (+)-sinactine, apocavidine, stylopine, (+)-cavidine, cheilanthifoline, and dehydrocavidine; two spirobenzylisoquinolines, yenhusomine and yenhusomidine; one phthalideisoquinoline, corlumine; one benzophenanthridine, dihydrosanguinarine and protopine, have been isolated

Three new tetrahydroprotoberberine N-oxide alkaloids, (-)- cis-corydalmine N-oxide, (-)- trans-corydalmine N-oxide, and (-)- trans-isocorypalmine N-oxide, along with three known benzo[ C]phenanthridine alkaloids, norsanguinarine, dihydrosanguinarine, and oxysanguinarine, six known berberine

UPLC-ESI-Orbitrap-MS/MS was used to analyze,identify and attribute the chemical constituents in Pudilan Antiphlogistic Oral Liquid. The analysis was performed on an Agilent Eclipse XDB-C18(4.6 mm × 150 mm,3.5 μm) with a gradient mobile phase of methanol-0.1% formic solution system at the flow rate
