J Asian Nat Prod Res. 2013;15(3):315-8. | A new antibacterial denitroaristolochic acid from the tubers of Stephania succifera.[Pubmed: 23418880] | METHODS AND RESULTS:
A new denitroaristolochic acid, demethylaristofolin C (1), together with six known alkaloids, crebanine N-oxide (2), (-)-sukhodianine-β-N-oxide (3), palmatine (4), Corydalmine (5), dehydroCorydalmine (6), and corynoxidine (7), was isolated from the tubers of Stephania succifera. The structure of demethylaristofolin C was elucidated by spectroscopic techniques (UV, IR, 1D, and 2D NMR) and HR-ESI-MS analyses.
CONCLUSIONS:
These compounds exhibited antibacterial activities against Staphylococcus aureus and methicillin-resistant S. aureus strains in different degrees. | Mycobiology. 2007 Jun;35(2):69-71. | Effect of 1-corydalmine,an Alkaloid Isolated from Corydalis chaerophylla Roots on Spore Germination of Some Fungi.[Pubmed: 24015073] |
METHODS AND RESULTS:
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, Helminthosporium species,H. penniseti and a Heterosporium species.
CONCLUSIONS:
1-Corydalmine significantly inhibited spore germination of all the fungi at 100 to 1500 ppm. It was effective against all the fungi at 1500 ppm. C. lunata was highly sensitive to this chemical even at 250 ppm. |
