Investigation of the lignins ofPhragmites communus Trin.

Summary

1. Lignin has been isolated from the stems ofPhragmites communus Trin. by the hydrochloric acid and the copperammonia methods. Its elementary composition and functional groups have been determined. The mean composition of the C6-C3 structural unit has been determined.

2. The oxidation of comminuted reed stems with nitrobenzene in the presence of alkali has given a mixture of aldehydes: syringaldehyde, vanillin, and p-hydroxybenzaldehyde. Their yield was 3–4 times less than from wood.
