Extended Data Fig. 7. HSQC spectra of FPL before and after hot-pressing.

Extended Data Fig. 7

a, b, Side-chain (a) and aromatic (b) regions in HSQC spectra of FPL before and after hot-pressing. c, Contents of the vacant sites on the aromatic nuclei of FPL before and after hot-pressing determined by HSQC. The hot-pressed lignins were prepared by hot-pressing FPL that were wrapped by aluminum foil under different temperatures; other hot-pressing conditions: lignin/water = 1: 2 (w: w), 8 min, pH = 7, and 1.5 MPa.
