title: Cardiac glycosides isolated from the Indian-snuff, Maquira sclerophylla Ducke.
abstract: The hydroalcoholic extract of the powdered bark of the Indian-snuff Maquira sclerophylla Duck was purified by column chromatography in silica-gel and the major cardenolide isolated from preparative TLC was identified by 1H-NMR, 12C-NMR and IR analyses. The spectra showed that the active substance has strophanthidin as the aglycone.
