natural compounds isolated from plants containing a sugar molecule.

Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed. (From Dorland, 28th ed; From Miall's Dictionary of Chemistry, 5th ed)

An organic substance which may be broken into two parts, one of which is always sugar.

Compound formed by the reaction of a sugar with a non-sugar molecule called the aglycone. Includes classes such as the anthoxanthin glycosides (plant pigments), the steroid glycosides, and the cyanogenic glycosides.

Chemical found in certain plants, often poisonous to animals.
