The previously published structure (5) of the alkaloid ipomine, from Ipomoea muricata Jacq., has been questioned. It has now been suggested that the signals from the sugar moiety in the n.m.r. spectrum should be re-assigned, and that ipomine is ipalbidinyl-(6-0-p-coumaroyl-/3-D-glucopyranoside) (6), and not the 4-0-p-coumaroyl-j8-D-glucopyranoside (5). The formulae (5) and (6) depicted... 

Seeds of Ipomoea muricata Jacq. from plants grown in Senegal afforded the known alkaloid ipalbidine in low yield (0.001%) and a new alkaloid ipomine (0.02%). Acid hydrolysis of ipomine gives ipalbidine, D-glucose, and p-coumaric acid, while enzymatic hydrolysis with emulsin yields ipalbidine. From a study of the hydrolysis products and spectroscopic data, ipomine has been shown to be 1-/3- ipalbidinyl-4-p-coumaroyl-D-glucopyranoside (1). ...
