Yield:520-33-2 88%

Reaction Conditions:

with sulfuric acid in ethanol;water; for 4 h;Reflux;

Steps:

Naringenin:

General procedure: Naringenin: Naringin (20 g) was dissolved in ethanol (150 mL, 80%),and conc. H2SO4 (10 mL) was added dropwise. The reaction mixturewas heated under reflux for 4 h, then cooled to room temperatureand poured into ice water. The resulting precipitate was filtered,recrystallised from methanol, and dried under vacuum to affordnaringenin as a yellow solid: 9.12 g; 90%;
