Abstract
Echinatin glycosides are disclosed having the following formula ##STR1## wherein R.sub.5 and/or R.sub.6 is a glycosyl residue. These substances have pharmacological effects such as the inhibiting action of the echinatin-4'-glucoside on the growth of human lymphoblastoids. These compounds may be chemically synthesized by subjecting a compound of the following formula ##STR2## to reaction with a compound represented by the following formula ##STR3## in which R.sub.1 and/or R.sub.2 is a glycosyl residue or an acyl glycosyl residue, with the optional successive step of subjecting the resultant to reaction with a glycosyl halide or an acyl glycosyl halide.
