| Abstract: | Arabinoglucuronoxylan is the main component in the hemicellulose of moso bamboo.The content of glucuronic acid which is as the main side chain can reflect the structure of the hemicellulose.In this paper,a method for the determination of glucuronic acid in hemicellulose of moso bamboo with m-hydroxydiphenyl was used.The amounts of tetraborate/H2SO4,m-hydroxydiphenyl and the boiling time were studied.This method was proved simple,accurate and reproducible. |

| Keywords: | hemicellulose moso bamboo glucuronic acid method of m-hydroxydiphenyl |
