phenomenon may be associated with the hydrophobic character
of the isoflavone forms, and the aglycones were more hydrophobic
when compared with b-glucoside conjugates, its solubility was
restricted in the aqueous Monascus aged vinegar.
The distribution of isoflavones in Monascus aged vinegar after
soaking for 24 h, including 327.6 mg/100 g malonyl derivatives,
35.96 mg/100 g acetyl conjugates, 120.8 mg/100 g b-glucoside conjugates
and 15.69 mg/100 g free isoflavones (aglycone forms). The
proportions of various isoflavone forms were 65.51% malonyl
derivatives, 7.19% acetyl conjugates, 24.16 b-glucoside, and 3.14%
aglycone forms. The proportion of isoflavones forms was similar
