摘要：

Two epimeric sesquilignans and two lignans were isolated from the sapwood of Tsuga heterophylla (western hemlock, Pinaceae). By spectroscopic analyses their structures were deduced to be (8R,8'R,7'R,8''S,7''R)-7'-hydroxylappaol E and (8R,8'R,7'R,8''S,7''S)-epi-7'-hydroxylappaol E, and (8'R,7'S)-8-hydroxy-alpha-conidendrin and (8'R,7'S)-8-hydroxy-alpha-conidendric acid ester. Their presence in several samples of western hemlock sapwood was confirmed by quantitative analyses. Copyright (C) 1997 Elsevier Science Ltd.
