Abstract

Chemical investigation of the twigs (separated from the needles) of the Himalayan yew, Taxus baccata, has culminated in the isolation of a new lignan, 4'-O-demethylsuchilactone, along with eight phenolic compounds, (−)-rhododendrol, (−)-rhododendrin, sciadopytisin, ginkgetin, kayaflavone, (−)-secoisolariciresinol, suchilactone and a lignan diol, not previously encountered in nature. Three taxoids, brevifoliol, 13-decinnamoyltaxchinin B and 10-deacetylbaccatin III were also isolated. This is the first report on the phytoconstituents isolated only from the twigs of the Himalayan yew.
