The structures of three glucosylsterols in a glycolipid mixture from the
product of the naturally dried medicinal plant Euryale ferox Salisb. have
been elucidated by 500 MHz nuclear magnetic resonance and mass
spectroscopic methods and characterized as follows: 24-
methylcholest-5-enyl-3 beta-O-pyranoglucoside, 24-ethylcholest-5-enyl-3
beta-O-pyranoglucoside, and 24-ethylcholesta-5,22E-dienyl-3 beta-O-
pyranoglucoside. These constituents may be the active substances of the
medicinal plant.
