| Abstract: | After feeding experiments of Myrica rubra young shoots with 4-8,9-13C2]coumaric acid, mass spectrometric analyses revealed that the cyclic diarylheptanoids, myricanol and myricanone, were derived
from two molecules of 4-coumaric acid. 13C Nuclear magnetic resonance analysis of myricanol isolated after administration of 4-8,9-13C2]coumaric acid demonstrated that the C-8 and C-9 atoms of 4-coumaric acid are incorporated into C-8, C-9, C-11, and C-12 of
the corresponding myricanol.
Part of this report was presented at the 56th Annual Meeting of the Japan Wood Research Society, Akita, August 2006 |
