Yields (wt%, based on the Klason lignin amount) of vanillin and vanillic acid from the Japanese cedar wood flour (14.0 mg) degraded in the Bu4NOH aq.-based reaction media (2.0 mL) at 120 ℃ and their yields from alkaline nitrobenzene (AN) oxidation
Reaction pathways from Lm2 to the products detected in this study. The formation of vanillic acid via pathway H is less significant than that via pathway G
