Abstract

Chromatographic investigation of the aglycones and sapogenins of the hydroysed powder of Sansevieria cylindrica leaves revealed the presence of 13 components, three of them were chromatographically identical to b-sitosterol, diosgenin and ruscogenin in various TLC systems. Preparative TLC and column chromatographic techniques were used for the isolation of the three oomponents. Their identity was confirmed by TLC, gas chromatography, IR, UV, NMR and mass spectral data. The compound corresponding to ruscogenin was stereochemically confirmed as 25S-ruscogenin by IR and NMR data.
