Fig. 6From: Fractionation and characterization of lignin streams from unique high-lignin content endocarp feedstocks13C–1H (HSQC) spectra of aromatic regions (left) and aliphatic region (right) of walnut CEL (WCEL), walnut DES extracted lignin (WDESL), peach CEL (PCEL) and peach DES extracted lignin (PDESL). The structures of lignin compositional units and side-chain linkages were coded with colors corresponding to the cross peaks in the spectraBack to article page
