  Taxifolin 3-arabinoside from Fragaria x ananassa

  摘要：

  From the roots of Fragaria x ananassa, a new flavonoid, (+)-taxifolin 3-O-alpha-L-arabinofuranoside was isolated and its structure was established on the basis of chemical and spectroscopic evidence. A hydrolysable tannin, pedunculagin, and condensed tannins, (+)-catechin, (+)-afzelechin-(4 alpha-8)-(+)-catechin, procyanidin B-3 and procyanidin B-6 were also isolated.
