Extracts of callus or cell suspension cultures from petioles of Ginkgo biloba catalyzed the production of (+)-gallocatechin (2,3-trans-3,5,7,3',4',5'-hexahydroxy-flavan) from (+)-dihydromyricetin (5'-hydroxy-dihydroquercetin) along with the expected 3,4-cis-diol intermediate, leucodelphinidin, in a...

Plant Physiol . 1984 Sep; 76(1):184-6. PMID: 16663794
Extracts of cell suspension cultures from Douglas fir (Pseudotsuga menziesii) needles catalyzed the production of (+)-catechin (2,3-trans flavan-3-o1) from the 2,3-trans-flavan,3,4-cis-diol (leucocyanidin) in a NADPH-dependent reductase reaction at pH 7.4....
