Reaction Steps
About 49.0 mg of genistin were refluxed in 15 ml 4N HCl for five hours at 105°±5° C. About 22.9 mg of genistein was obtained with about 75% recovery. About 13 mg genistein from the previous step was extracted twice with 50 ml diethyl ether. The extracts were combined, and evaporated to dryness. The solids obtained were crystallized from 2 ml of a solution made from 3 parts ethanol and 2 parts water. About 8.2 mg of the genistein crystal was obtained with 63% recovery and about 99% purity.
