摘      要：The most abundant phenolic biopolymer in the biosphere is the *** phenolic biopolymer commonly exists in combination with polysaccharides and other cell wall *** this study,the solvent system dioxane-water is used to extract lignin,which is considered as unaltered native *** dioxane lignin extracted from fig stems was characterized regarding to its structural feature,quantification of its functional groups,molecular weight,and evaluation of its thermal *** and molecular weight distribution of the studied lignin indicated that isolated lignin contained a low amount of sugar(c.a.19%)and had a high weight-average molecular weight(10068 ***-1).Lignin sample had approximately the same amounts of guaiacyl(G)and p-hydroxyphenyl(H)units with relatively fewer syringyl(S)*** isolated lignin revealed good antioxidant ***,it proved to have a high potential of application in new antioxidants formulations.
