Two monoacylated glycosides have been isolated from the needles of Picea obovata - the previously unknown 3''-p-coumaroylastragalin (I) and 6''-p-coumaroylastragalin (II).It has been established that under the conditions of mild saponification and acid hydrolysis isomerization of (I) into (II) and the splitting out of the acid residue takes place.The position of the acyl substituent has been shown by PMR spectroscopy using the INDOR method.The physicochemical characteristics of the acylated glycosides and of their heptaacetates are given.
