ABSTRACT

The hydroalcoholic extract of the powdered bark of the Indian-snuff Maquira sclerophylla Ducke was purified by column chromatography in silica-gel and the major cardenolide isolated from preparative TLC was identified by 1H-NMR, 1 2 C-NMR and IR analyses. The spectra showed that the active substance has strophanthidin as aglicone.
