From: A rapid thioacidolysis method for biomass lignin composition and tricin analysis

Lignin composition of bagasse and cottonwood samples. a. Average lignin S/G ratios measured by original and modified thioacidolysis (n = 8). Values obtained with the two methods are not statistically different (p > .05); b. Average Lignin S/G ratios measured by the modified method of the same samples (n = 6) in four different experiments. No significant differences were observed between experiments (p > .05)
