Genistein, namely genistein, is a rectangular or hexagonal rod-shaped crystal (60% ethanol) and dendritic crystal (ether), with a melting point of 297-298 ℃ (slightly decomposed). Soluble in DMSO and ethanol, almost insoluble in water. The solubility in water is 8.7 μ g / ml. changing the pH of the solution has no significant effect on genistein.
Genistein, derived from Sophora japonica,
Physical properties: gray white dendritic needle crystal powder. mp297℃-298℃; Soluble in common organic solvents, almost insoluble in water and soluble in dilute alkali.
