Abstract
Abstract High levels of the stilbene glucosides astringin and isorhapontin, previously identified as major constitutive antifungal compounds in Sitka spruce ( Picea sitchensis ), were present in mature bark tissues. Levels in needles, sapwood and feeder roots were relatively low. Significant amounts of the aglycones astringenin and isorhapontigenin were not found in healthy spruce tissues. In the bark the stilbenes were present at high levels in certain parenchyma cells: the relative proportions of the two glucosides, as well as absolute amounts varied from the cambium to the periderm.
