Abstract
Natural and isolated lignins of the algaCystoseira barbata of different ages have been cleaved with metallic sodium in liquid ammonia. Nine compounds were identified in the cleavage products by GLC: derivatives of the p-coumaryl and guaiacyl series with free OH groups in the α and γ positions of the side chains of the aromatic nucleus. It has been shown that with the growth of the alga the lignin becomes less condensed, which may be due to an increase in the degree of its methoxylation.
