Figure 6. Incorporation of tritiated phenylalanine into the compound middle lamella lignin and the secondary wall lignin determined by counting the silver grains. Symbols are as follows 0, compound middle lamella 0> secondary wall. Figure 6.

Procedure. Ignite the dried crucible and residue from the lignin determination for 3 h in a furnace at 500°C. Allow to cool in a glass desiccator and weigh. [Pg.127]

Yasuda and Terashima (11) recently showed that lignin under Klason lignin determination conditions afforded mefa-linked products. Vanillyl alcohol (4) yielded after reflux in 5% sulfuric acid, mefa-linked product (8) (Fig. 3). [Pg.350]

Table 4.4.1 gives the distribution of lignin in Douglas-fir (Pseudotsuga menziesii) earlywood tracheids (Saka and Thomas 1982). The overall lignin content (W) of the earlywood portion is 0.285 gig). The Klason and acid-soluble lignin determinations should be made on wood taken near the location from which the sections are collected for EDXA measurements. [Pg.140]
