The absolute configurations of four hydroxyfatty acids, jalapinolic acid, convolvulinolic acid, ipurolic acid and 3, 11-dihydroxyhexadecanoic acid, obtained by acid hydrolysis of various resin glycosides, have been determined to be 11S, 11S, 3S, 11S, and 3S, 11S, respectively, by Mosher's method. The R-configuration of jalapinolic acid previously defined by Horeau's method was therefore revised to S.
