In order to enhance the utilization of kenaf stems, chemical stabilities against hydrothermal reactions were compared between core parts and bast ribbons. With increasing the treatment temperature, hemicellulose fractions contained in the intercellular matrix regions were preferentially decomposed. This tendency was more markedly observed when the treatments were applied to kenaf core parts. It seems that LCC(Lignin carbohydrate complex)in the intercellular matrix regions are constructed by settling hemicellulose fractions on the backbone of lignin via calcium complex bonding.
