Fig. 6From: Characterization of lignin-derived products from Japanese cedar as treated by semi-flow hot-compressed waterMALDI-TOF/MS spectra of the lignin-derived products in the water-soluble portion for the 1st (upper) and 2nd stages (lower) (m/z: 500–1400). Several molecular weight intervals (MWI) of about 178.20 and 196.20 were obtained from the 1st stage water-soluble portion, suggesting β-β or β-5, and β-O-4 linkages, respectivelyBack to article page
