Table 4.
Water-solubility of daidzein (1) and its β-glycosides 2–5.
Compound | Water-Solubility (μmol/mL) | Fold a |
---|---|---|
1 | 1.2 × 10−3 | 1 |
2 | 3.5 × 10−2 | 29 |
3 | 4.0 × 10−2 | 33 |
4 | 0.2 | 183 |
5 | 1.0 | 850 |
Fold of water-solubility of glycosides 2–5 is expressed relative to that of their aglycone 1, normalized to 1.
