Reaktionsschritte

Five grams of naringin are dissolved in 25 ml of a 10% aqueous solution of potassium hydroxide and hydrogenated at room temperature and at atmospheric pressure, using 500 mg palladium black as catalyst. The resultant colorless solution is diluted with water; after removal of the catalyst the solution is passed through an Amberlite 200 (Rohm & Haas) column, and the alkaline-free eluate is evaporated to dryness. White crystals of the dihydrochalcone of naringin are obtained, m.p. 169°-170° C, in a yield of 98%.
