Thuja plicata Donn

Another example is illustrated in Figure 9 (27). The outer, sap-wood rings of a western redcedar, Thuja plicata Donn, which grew about 50 miles south of Seattle, show an increase in 14C which lags slightly behind the levels of 14C which prevailed in the atmosphere. This lag is attributed to a holdover of food supply from the previous year a sizeable...

Hemicelluloses from many woods, particularly conifers (softwoods) contain glucomannoglycans which may be isolated by fractionation procedures. The glucomannoglycan from western red cedar [Thuja plicata Donn) is a typical example. It contains D-glucose and D-mannose only, in the ratio 2 5, and is a short-chain, essentially linear, /S-d-(i - 4)-linked polymer. Similar glucomannoglycans have been isolated from western hemlock [Tsuga heterophylla), sitka spruce (Picea sitchensis) and other softwoods. Glucomannoglycans from Norwegian spruce (Picea aHes) are a-D-(i - 4)-Unked.
