英文摘要

One monomer flavan-3-ol, 4 alpha-carboxymethyl-(+)-catechin methyl ester, two monomer flavan-3-ol glycosides, (+)-afzelechin-3-O-beta-allopyranoside, (+)-afzelechin-6-C-beta-glucopyranoside, two dimer flavan-3-ols, (-)-epiafzelechin-(4 beta -> 8)-4 beta-carboxymethyl-(-)-epicatechin methyl ester, and -(-)-epiafzelechin-(4 beta -> 8)-4 alpha-carboxymethyl-(-)epiafzelechin ethyl ester, and one trimer flavan-3-ol, (-)-epiafzelechin-(4 beta -> 8)-(-)-epiafzelechin-(4 beta -> 8)-4 beta-carboxymethyl-(-)-epiafzelechin methyl ester, together with thirteen known flavan-3-ols were isolated from the rhizomes of Drynaria fortune′ (Kunze) J.Sm (Polypodiaceae). The structures were established by analysis of their HRESIMS, 10,20 NMR spectroscopic, and CD data. In order to obtain improved resolution, the high-resolution NMR spectra of the dimers and trimer were measured at -40 degrees C. (C) 2011 Elsevier Ltd. All rights reserved.
