1-Corydalmine,an alkaloid isolated from roots of Corydalis chaerophylla inhibited spore germination of some plant pathogenic as well as saprophytic fungi e.g. Alternaria brassicae, A. brassicicola, A. solani, Curvularia lunata, C. maculans, C. sp., C. pallscens, Erysiphe pisi, Fusarium udum,
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
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
