Nomenclature: ending in IN for trivial names
 Digitoxin– Digitalis
 Salicin– Salix
 Prunasin– Prunus
 Systematic naming replacing OSE suffix of the parent sugar with OSIDE.
 Anoremic prefix (alpha/beta) and the configurational prefix (D/L) immediately precede the sugar stem name, and the chemical name of the aglycone precedes the name of the sugar.
