Determination of 2-deoxyaldoses and their natural glycosides with the aid of xanthydrol

  • Published:
Chemistry of Natural Compounds Aims and scope

Summary

The molecular extinction coefficients in the xanthydrol reaction of 2-deoxyaldoses and their cardenolide glycosides have been measured. The absorption indices vary within wide limits according to the structure of the sugars. The 2,6-dideoxyaldoses have a considerably higher coefficient than the 2-deoxyaldoses. Disaccharides in which 2,6-dideoxyaldohexoses are attached to the D-glucose show a comparatively low optical density. The glycosides reflect the properties of the sugars that they contain.

A rough method of determining the amount of pregnane glycosides in plants has been developed.
