Abstract

Three new hydrolyzable tannins, rugosins A (1), B (2) and C (3), were isolated from flower petals of Rosa rugosa thunb. (Rosaceae), and their structures, including the orientation of the valoneoyl group, were established based on chemical evidence and spectroscopic analysis, utilizing two-dimensional nuclear magnetic resonance spectral data.
