Abstract Spectrophotometry was used to determine the total fla vone co ntent in Ilicis Folium leaf according to the fact that the maximum absorbency ca n be obtained when the chelate formed by the combination of flavonoids and metal ion is at 510 nm. The result has shown that the method for determination of the total flavone content in Ilicis Folium leaf is easy to handle and reliable with satisfactory result.
