Aim To study the NMR characteristics of a new class of highly aromatic cholestanoid steroid sapogenin. Methods The 1D- and 2D-NMR techniques were used to determine the NMR data of high-aroma cholestya-saponins. The data were analyzed based on the literature data. Results All NMR signals for this type of compound aglycone are clearly assigned. Conclusion The high-aromatic cholestane-type steroidal sapogenin has a clear NMR character and provides an important reference for the structural identification of this type of compound.
