Abstract
Three new complex tannins, stachyuranins A (1), B (2) and C (3), were isolated from the leaves of Stachyurus praecox (Stachyuraceae), and their structures, each consisting of a catechin or gallocatechin residue and a monomeric hydrolyzable tannin moiety, were assigned. Structures 1 and 2 lack a C-C linkage between glucose C-1 and the aroyl group at glucose 0–2, suggesting that they may be biogenetic precursors of complex tannins with the C-C linkage.
