Trojanosides I-K: new cycloartane-type glycosides from the aerial parts of Astragalus trojanus.
Three new cycloartane-type triterpene glycosides have been isolated from the aerial parts of Astragalus trojanus. The structures were established mainly by a combination of one- and two-dimensional NMR techniques [1H-1H-correlation spectroscopy (COSY), 1H-13C-heteronuclear multiple quantum correlation spectroscopy (HMQC), and 1H-13C-heteronuclear multiple-bond correlation spectroscopy (HMBC)] a...

متن کاملNew flavonolignan glycosides from the aerial parts of Zizania latifolia.
Two new flavonolignan glycosides, tricin-4'-O-(threo-β-guaiacylglyceryl) ether 7''-O-β-D-glucopyranose (4) and tricin-4'-O-(erythro-β-guaiacylglyceryl) ether 7''-O-β-D-glucopyranose (5) were isolated from the roots of Zizania latifolia, together with tricin-7-O-β-D-glucopyranose (1), tricin-4'-O-(threo-β-guaiacylglyceryl) ether 7-O-β-D-glucopyranose (2), and tricin-4'-O-(erythro-β-guaiacylglyce...
متن کاملTwo new cycloartane glycosides from the underground parts of Aquilegia vulgaris.
Two new cycloartane glycosides, named aquilegiosides K and L, have been isolated from the dried underground parts of Aquilegia vulgaris. Their structures were determined by two dimensional (2D) NMR spectroscopic analysis and chemical evidence.
