The epigeaI part of Elaeagnus angustifolia L. (Russian olive) collected in the flowering period in the environs of Zaporozhe has been investigated in order to determine its content of phenolic compounds. The leaves were extracted with ethanol, and the aqueous residue was purified with chloroform, acidified with 15% sulfuric acid to pH 2-3, and extracted with ethyl acetate. By preparative paper chromatography, the ethyl acetate extracts yielded substances I, II, and III, giving positive qualitative reactions for phenolcarboxylic acids, their Rf values being, respectively, 0.28, 0.52, and 0.65 {0.1 N HC1 system).
