isocorypalmine/キケマン属

A new alkaloid, chaerophylline (1), together with known alkaloids (-)-corypalmine, berberine chloride, (-)-isocorypalmine, (-)-corydalmine and (+)-bicuculline have been isolated from the crude base fraction of Corydalis chaerophylla. The crude base fractions of Corydalis longipes gave a new

Protoberberine alkaloids from the rhizomes of Corydalis cava were investigated with regard to their influence on the GABA A receptor using radioreceptor assays. Whereas the protoberberine type 2 alkaloids, isoapocavidine, corydaline, tetrahydropalmatine, scoulerine and isocorypalmine, increased the

Bioactivity-guided fractionation of Corydalis yanhusuo has resulted in the isolation of eight known isoquinoline alkaloids - tetrahydropalmatine, isocorypalmine, stylopine, corydaline, columbamine, coptisin, 13-methylpalmatine, and dehydrocorybulbine. The tertiary alkaloids were further analyzed by

A new tetrahydroprotoberberine N-oxide alkaloid, (-)-cis-isocorypalmine N-oxide (1), together with two known compounds, 6-methoxydihydrosanguinarine (2) and norjuziphine (3), were isolated in continuing studies of the entire Formosan Corydalis tashiroi plant. The structures of these three compounds

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
