Steroidal glycosides from Digitalis ciliata leaves

摘要

Two new steroidal glycosides of the spirostane and furostane classes, derivatives of gitogenin, were found in wastes from producing acetyldigitoxin preparation from Digitalis ciliata Trautv. (Scrophulariaceae). The structures of the glucosides were established using physical constants, chemical transformations, and IR, mass, and NMR spectra.
