Of the seven triterpene glycosides present in the leaves of Hedera colchica C. Koch, (ram. Araliaceae) -Colchis ivy, which we have called hederacolchisides, we have previously isolated and characterized the three most polar [i, 2]. In continuation of these investigations, we have succeeded in isolating another three, comparatively nonpolar, compounds present in the total in minor amount -hederacolchisides A', A, and C.Complete acid hydrolysis showed that glycosides A' and C, with mp 222-226 and 168-176°C (decomp.), respectively, were derivatives of oleanolic acid, while glycoside A, with mp ±68-176°C (decomp.), was a hederagenin derivative. By PC and TLC, and by the GLC of the monosaccharides in the form of their polyol acetates on a Chrom-5 instrument [3], it was establishedthat the carbohydrate moieties of hederacolchisides A' and A contained rhamnose, arabinose, and glucose residues in a ratio of i:i:i, and that of hederacolchiside C contained the same residues in a ratio of 2:1:2.According to the results of UR spectroscopy and alkaline hydrolysis, in glycosides A' and A the monosaccharides were attached in position 3 of the aglycons, while in glycoside C an ester bond was found, in addition.The determination of the complete chemical structures of the glycosides isolated is continuing.
