Quantitative Determination of Ferulic and p-Coumaric Acids in Cell Wall of Moso Bamboo Green and Bamboo Yellow
摘要
Abstract
Moderate alkali hydrolysis and acid hydrolysis were applied to quantitatively determine the amount of ferulic and p-coumaric acid in the cell wall of Moso bamboo green and bamboo yellow .The results indicated that 3.07%of ferulic acid and 5.91%of p-coumaric acid were found in the bamboo green cell wall .And 1.61%ferulic acid and 4.64%p-coumaric acid were ester-linked to the bamboo green cell wall components , while 1.46%ferulic acid and 1.27%p-coumaric acid were ether-linked to the cell wall component .For bamboo yellow, there were 3.11%of ferulic acid and 5.51%of p-coumaric acid.The amounts of ester-linked and ether-linked ferulic acid were 1.71%and 1.40%, respectively.And the amounts of ester-linked and ether-linked p-coumaric acid were 4.34% and 1.17%, respectively.Two-dimensional heteronuclear single quantum correlation nuclear magnetic resonance (2D-HSQC NMR) confirmed that the ester-linked ferulic and p-coumaric acid in the alkaline-soluble lignins of bamboo green and bamboo yellow might be esterified in the γposition of β-O-4 aryl ether bonds in the lignin .关键词
