Four ether-soluble resin glycosidses (jalapins), marubajalapins VIII-XI previously obtained from the aerial part of Pharbitis purturea, were characterized on the basis of chemical and spectral data. All of them and marubajalapin VII reported in the previous paper are mutually positional isomers composed of 3 mol of n-octanoic acid and 1 mol of operculinic acid E having a macrocyclic ester structure.
