Total extractive percentage (TE) = (weight of the oven dry extractive residue/weight of the original fiber sample) x 100
Ash percentage (A)=(weight of the oven dry ash residue/weight of the original fiber sample)x 100
Cellulose percentage (C) =weight of the oven dry cellulose residue/weight of the original fiber sample)x 100
Total lignin percentage (TL)= (percentage of soluble lignin + percentage of insoluble lignin)
Percentage of polysaccharides including hemicelluloses (H)= 100 - (TE+ A+ C+ TL)
