摘要：
Two enzyme assays using either radiolabelled or non-labelled substrates were applied to detect dihydroflavonol 4-reductase (DFR) activity in lignocellulosic tissues. The successful detection of DFR in these tissues rich in polyphenols relied on the addition of sufficient amounts of polyethylene glycol. DFR activity is measured in sapwood and inner bark of different conifer species. (C) 1997 Elsevier Science Ltd. All rights reserved.
