Oligomeric hydrolyzable tannins belong to a newly developed field of tannin research. The isolation and structure determination of the first oligomer, agrimoniin, were presented in 1982, and since then more than sixty oligomers have been obtained from various plants by 1989. This review deals with these oligomers which were classified according to the biogenetical coupling modes between monomeric hydrolyzable tannins, and their botanical sources. Recent techniques for their isolation and structure elucidation, and the biological activities of the oligomers are also discussed.
