Abstract
Two new phenol glycosides forsythoside F (1) and forsythoside G (2) have been isolated from Forsythia viridissima stems and their structures were established based on the spectroscopic data and chemical transformations. D-2-O-methylapiose was for the first time characterized in the natural product.
