Five new ether-soluble resin glycosides were isolated from whole plants of Ipomoea stalonifera. Their structures have been determined on the basis of chemical and spectral data. Similar to the resin glycosides previously isolated, all of them are monomers of a jalapinolic acid tetra- or penta-glycoside in which the sugar moiety is partially acylated by organic acids and also combined with the carboxy group-of the aglycone to form a macrocyclic ester structure.
