Procyanidin B-5 (1), epicatechin-(4β→8)-epicatechin-(4β→6)-epicatechin (2), and epicatechin-(4β→6)-epicatechin-(4β→8)-epicatechin-(4β→6)-epicatechin (3), which showed an inhibitory effect toward protein kinase C, were isolated from the rhizomes of Davallia mariesii MOORE. Detailed analyses of their ¹H- and ¹³C-nuclear magnetic resonance spectra were carried out by the use of two-dimensional nuclear magnetic resonance techniques.
