Figure 3

The PCA (a), NMDS (b), and RDA (c) analysis. Note: In (a) and (b), S1A, S1B, and S1C represent the fermentation triplicate of buckwheat honey sample S1. FOSA, FOSB, and FOSC represent the fermentation triplicate of positive control fructooligosaccharides. BLKA, BLKB, and BLKC represent the fermentation triplicate of blank control. ORIA, ORIB, and ORIC represent the fermentation triplicate of the human original microbes. (c): 1. protocatechuic acid; 2. 4-hydroxy benzoic acid; 3. 4-hydroxybenzaldehyde; 4. vanilin; 5. gallic acid; 6. p-coumaric acid; 7. benzoic acid; 8. ferulic acid; 9. isoferulic acid; 10. methyl syringate; 11. trans,trans-abscisic acid; 12. cis,trans-abscisic acid. a. fructose; b. glucose; c. kestose; d. isomaltose; e. isomaltotriose; f. panose.
