Milled wood lignin (MWL) was isolated from Dendrocalamus sinicus, an abundant bamboo variety in the earth, using Bjorkman method. Elucidation and quantification of the chemical structures for the isolated MWL have been facilitated by employing FT-IR and NMR techniques. The obtained results showed that the MWL consists of syringyl (S), guaiacyl (G), and p-hydroxyphenyl (H) units, indicating it as grass type (HGS) lignin. There is no significant change in structure (i.e. cleavage at α-O-4′ and β-O-4′ linkage) was observed. NMR techniques indicated that the isolated lignin was rich in β-O-4′ aryl ether substructures and syringyl (S) units. Furthermore, the sufficient understanding of the chemical structure of the lignin benefits their effective utilization towards the production of renewable biomass and biofuels.

使用Bjorkman方法从地上丰富的竹子Dendrocalamus sinicus中分离出磨碎的木质素（MWL）。通过使用FT-IR和NMR技术，已经为分离的MWL的化学结构的阐明和定量提供了便利。所得结果表明，MWL由丁香基（S），愈创木基（G）和对羟基苯基（H）单元组成，表明其为草型（HGS）木质素。没有在结构显著变化（即切割位在α-O- 4'和β -O- 4'键）进行了观察。NMR技术表明，分离出的木质素富含β- O-4'芳基醚亚结构和丁香基（S）单元。此外，对木质素化学结构的充分理解有利于木质素在生产可再生生物质和生物燃料方面的有效利用。
