BIARYLHEPTANOIDS AND OTHER CONSTITUENTS FROM WOOD OF ALNUS JAPONICA

Article abstract of DOI:10.1016/0031-9422(81)83035-X

The wood of Alnus japonica has been shown to contain a number of biarylheptanoids as well as other phenolics, including secoisolariciresinol diferulate.The co-occurence of cyclized biarylheptanoids with their corresponding acyclic biarylheptanoids has been demonstrated and this fact may have biosynthetic significance.The possible chemotaxonomic importance of biarylheptanoids in members of the Betulaceae is discussed.The isolation and identification of several steroids and triterpenoids are also described.Key Word Index- Alnus japonica; Betulaceae; new biarylheptanoids; biosynthesis; chemotaxonomy; secoisolariciresinol diferulate; steroids; oleanan triterpenoids.
