  1. 1.

    Biosynthetic lignins have been obtianed by Freudenberg's method from coniferyl and p-coumaryl alcohols.

  2. 2.

    In its elementary and functional composition, DHP-1 is similar to the corresponding material obtained by Freudenberg.

  3. 3.

    For DHP-1 the yield of ether-soluble phenols is considerably higher than for DHP-2, which may indicate a greater degree of condensation of the latter as compared with the former.

  4. 4.

    Reductive decomposition by a solution of metallic sodium in liquid ammonia has shown that the phenols obtained from reed lignin have a complex composition.

  5. 5.

    A comparison of the IR and UV spectra of the biosynthetic lignins obtained and of reed and spruce MWLs has been performed.
