From bulbs of Ornithogalum nutans L. (2n = 30) nineteen cardenolides were isolated by column chromatography and TLC. Thirteen substances were structurally elucidated as glycosides of Strophanthidin, Sarmentosigenin, Sarmentogenin, Bipindogenin, 2alpha-Hydroxy-bipindogenin, Syriogenin, 7alpha-Hydroxy,12-oxo,8beta,14beta-epoxy-uzarigenin, 3beta,11beta-Dihydroxy, 12-oxo,18-nor-5alpha-card-13-enolide, 3beta,11beta-Dihydroxy,12-oxo,18-nor-5alpha-carda-13,20(22)-dienolide, mainly by means of H-1, C-13 NMR spectroscopy, FAB-MS and identification of the sugar moieties by GLC after acid hydrolysis of the cardenolides. Six of these glycosides were identified by cochromatography (HPLC and TLC) with authentic samples. The results obtained were discussed with regard to the close botanical relationship of Ornithogalum nutans L. and Ornithogalum boucheanum (KUNTH) ASCHERS.
