Abstract
In this study, the structral characteristics of bamboo lignophenol were discussed in detail. As a part of p-hydroxyphenolic units (H units) esterified to native core lignin still remained in ligno-p-cresols, the separation of H units from core lignin has been done in alkali conditions. The structure analysis of hydrolyzed H units is done with UV spectroscopy measurement(UV), Fourier Transform Infrared(FT-IR) etc.. They are composed of p-coumaric acid, ferulic acid and 4-hydroxybenzoic acid. p-Coumaric acid has antioxidant properties; ferulic acid, being highly abundant, may be useful as a precursor in the synthetic chemistry industry; p-hydroxybenzoic acid is primarily known as the basis for the preparation of cosmetics. That is, p-coumaric acid and ferulic aicd and p-hydroxybenzoic acid are important as the industrial raw materials such as the medicine, the spices, and cosmetics. Therefore, the potential of bamboo forest as a sustainable molecule forming fields can be evaluated through the phase-separation system by the performance analysis on a molecular refining characteristics.
