Eucommia ulmoides

Incubation of coniferyl alcohol with a crude enzyme preparation from Eucommia ulmoides in the presence of hydrogen peroxide resulted in optically active C8-0-C4 neolignan dimers, (+)-eryf/rro-guaiacylglycerol-( >-coniferyl ether (38% e.e.), and (-)-t/ire<9-guaiacylglycerol- 3-coniferyl ether (34% e.e.) (Fig. 12.11) [68]. In... [Pg.192]
