Glucosylsterols in extracts of Euryale ferox identified by high resolution NMR and mass spectrometry.
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.
