Abstract

Oligomeric procyanidins were isolated from the leaves and flowers of hawthorn (Crataegus laevigata). A trimer, epicatechin-(4β→8)-epicatechin-(4β→6)-epicatechin, and a pentamer consisting of (−)-epicatechin units linked through C-4β/C-8 bonds have been isolated from hawthorn for the first time, in addition to known procyanidins including dimers B-2, B-4 and B-5, trimers C-1 and epicatechin-(4β→6)-epicatechin-(4β→8)-epicatechin, and tetramer D-1.
A fraction containing a hexamer was also found.

Two procyanidins were isolated from hawthorn and identified as an epicatechin trimer with 4β→8 and 4β→6 bonds 6, and an epicatechin pentamer with 4β→8 bonds 9.
