This study aimed to find analytical data base for Iraqi phoenix date palm pruning woods. Lignin has been extracted for five  types of Iraqi date palm using Klason lignin method. Weight of extracted lignin ranged from ( 0.350 g – 0.698 g), and lignin % ranged from (17.5 – 34.9). (waxes, oils, resin, and proteins of wood gums) % ranged from (22.5 – 44.5). FT– IR Characterization showed that the (-OH) phenolic dis appear in all studied lignin samples, and the (4-O-5 inter monomeric lignin linkage) showed strong intensity peaks for Khadrawi, and Jamal AL-Deen samples, and moderate  intensities for Maktom, Barhi at, and Fahal. Also (DODO inter monomeric lignin linkage) showed strong intensity peaks for all studied samples. UV – Vis. Characterization showed that the lowest absorption maximum (254 nm) corresponds to Fahal lignin sample, While the highest absorption maximum (275 nm) corresponds to Jamal AL-Deen lignin sample.

Keywords: Milled Iraqi Phoenix, pruning woods, lignin, Quantitative Determination.
