Four new and two known ether-soluble resin glycosides were isolated from popular sweet potato (the roots of Ipomoea batatas L. LAM., Kokei 14 go, Convolvulaceae) in Japan. Unlike ester-type dimers, batatins I and II, obtained from other sweet potato (Ipomoea batabas var. batatas), the glycosides were tetra or pentasaccharide monomers in which the sugar moieties are partially acylated by organic acids and combine with the aglycone, jalapinolic acid, to form a macrocyclic ester.
