Abstract

A new resin glycoside, named muricatin IX (1), was isolated from the seeds of Ipomoea muricata (L.) JACQ. (Convolvulaceae). The structure of 1 was determined on the basis of spectroscopic data as well as chemical evidence. Compound 1 is the first representative of resin glycosides in which an organic acid connects the sugar moiety and the aglycone moiety to form macrocyclic ester ring.
