Two new hydrolyzable tannins, schimawalins A (10) and B (17), have been isolated from the dried flowers of Schima wallichii (DC) KORTH. (Theaceae), and their structures, having a dilactonized valoneoyl group in the molecule, were established based on spectral and chemical evidence. Eight known hydrolyzable tannins, including camelliin B (8), the main constituent of the flower, with a macrocyclic dimer structure, were also isolated. The orientation of the valoneoyl groups in camelliin B was completely determined.
