“…Particularly, 14 ketone compounds such as kaempferol 7-cellobioside 3-sophoroside, luteolin-7-O-glucoside and hesperetin were significantly down-regulated, probably because they were converted to other substances under different microorganisms and fermentation conditions or used as growth energy by fungi during the fermentation ( Xiao, Yang, et al, 2021 ). Many increased compounds mentioned in the present research, such as kaempferol, hesperidin, quercetin 3-O-malonylglucoside and xanthohumol, are well proven to exert potent antioxidant and anti-diabetes effects ( Choi, Lee, & Lee, 2022 ; Katsube et al, 2006 ; Zhang et al, 2023 ; Zhu et al, 2023 ). Therefore, many phenolic and flavonid compounds enhanced during SSF may be one of the reasons for the increased antioxidant activity of buckwheat.…”
