text: HBSL-base lignin at this peak had weaker values and reduced intensity compared to HBSL-acid lignin or EAL, and HBSL-acid lignin at this peak had weaker values than EAL, indicating that lignin extracted by HBSL-base method had the least =C-O-C group, HBSL-acid lignin the second, and EAL the most.
