Detection of lignans in western hemlock by radiography

  • Published:
Wood Science and Technology Aims and scope Submit manuscript

Summary

Evidence of the detection by radiography of α-conidendrin and hydroxymatairesinol, major lignans of western hemlock wood, is presented. Advantages of this new technique to wood chemists, as well as implications to wood technologists in terms of erroneous measurement of the specific gravity of unextracted wood by X-ray densitometry, are discussed.
