Abstract

Six kinds of so-called resin glycoside, muricatins I-VI, were isolated from the seeds of Ipomoea muricata JACQ. (Convolvulaceae). Their structures including the stereochemistry have been determined on the basis of chemical and spectral data. Similar to the resin glycosides previously isolated from the roots of I. orizabensis (PELLET) LEDAN., all of them were monomers of a jalapinolic acid tetraglycoside 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.
