Abstract

Three new cyanoglycosides named hydracyanosides D (1), E (2), and F (3) were isolated from the leaves of Hydrangea macrophylla cultivated in China together with 17 known constituents including hydracyanoside A (4). Their structures were elucidated on the basis of chemical and physicochemical evidence.
