title: Novel steroidal components from the underground parts of Ruscus aculeatus L.
abstract: Two new furostanol saponins 1&#8211;2 and three new sulphated glycosides 3a,b and 4 were isolated from the underground parts of Ruscus aculeatus L., along with four known furostanol and one spirostanol saponins 5&#8211;9 and three free sterols. All of the structures have been elucidated on the basis of spectroscopic data 1D and 2D NMR experiments, MS spectra and GC analyses.
