Structural elucidation and NMR spectral assignment of three new furostanol saponins from the roots of Tupistra chinensis.
Three new furostanol saponins (1-3) were isolated from the roots of Tupistra chinensis (T. chinensis). And their structures were elucidated on the basis of NMR and mass spectrometry (MS) spectral analysis.
