Abstract

Understanding the chemical structural differences of key components at varying bamboo heights enhances knowledge of its biological properties and adaptive mechanisms, promoting its high-value utilization. In this study, lignin and lignin-carbohydrate complexes (LCC) were extracted from the base, middle, and top sections of bamboo culms, and the chemical composition, micro-regional distribution, and structural characteristics of key components were analyzed. Results showed that both lignin and hemicellulose contents followed the trend: top > base > middle. The size and number of fiber cells decreased progressively from the base to the top, with lignin content most abundant in the cellular tissues at the top, where the S/G structural unit ratio was also the highest. Lignin-ferulic acid (FA)-carbohydrate complexes were identified as major recalcitrant structures in LCCs across different bamboo heights. These findings offer key insights into the chemical structural differences of lignin and LCCs at various bamboo heights, providing a scientific foundation for understanding bamboo's biological characteristics and facilitating its high-value applications.
