Characterization of Five Kinds of Wood Vinegar Obtained from Agricultural and Forestry Wastes and Identification of Major Antioxidants in Wood Vinegar

After publication of our article[1], it came to our attention that there were errors in some of the figure legends. The legend to Fig. 2 was incorrect. The corrected legend to Fig. 2 is given below. Fig. 2 VCEACs of wood vinegar andf ractions from wood vinegar WV1: oak wood vinegar; WV2: walnut shell wood vinegar; WV3: peanutshell wood vinegar; WV4: ricehuskwood vinegar; WV5: corn cob wood vinegar. The concentration of WV: 10 mL/L. The presentation of r values in Fig. 3(D), Fig. 4(D), Fig. 4(E) and Fig. 4(H) were incorrect. The corrected r values are given below. Fig. 3(D): r=−0.6800, Fig. 4(D): r=−0.9837, Fig. 4(E): r=−0.1714, Fig. 4(H): r=−0.1005. The legend to Fig. 3 was uncomplete. The corrected legend to Fig. 3 is given below. Fig. 3 Regression equations and Pearson’s correlation coefficients between the contents of components in phenolic extractives and VCEACs of phenolic extractives (n=3, R=adjustedr2) (A) Total phenolic compounds; (B) 2-methoxyphenol; (C) 2,6-dimethoxyphenol; (D) phenol; (E) 1-(4-hydroxy-3-methoxyphenyl)-2-propanone; (F) 3-methyl-1,2-cyclopentanedione; (G) 2-methoxy-4-methyl-phenol; (H) 4-ethyl-2-methoxy-phenol; (I) 4-methylphenol. The legend to Fig. 4 was uncomplete. The corrected legend to Fig. 4 is given below. Fig. 4 Regression equations and Pearson’s correlation coefficients between the contents of components in five kinds of wood vinegar and VCEACs of five kinds of wood vinegar( n =3, R =adjusted r 2 ) (A) Total phenolic compounds; (B) 2-methoxyphenol; (C) 2-methoxy-4-methyl-phenol; (D) phenol; (E) 4-methylphenol; (F) 4-ethyl-2-methoxyphenol; (G) 2,6-dimethoxyphenol; (H) 1-(4-hydroxy-3-methoxyphenyl)- 2-propanone; (I) 3-methyl-1,2-cyclopentanedione; (J) 2-methylphenol.
