Abstract:: Taking 1～3 years old Licoric as material，using 70% ethanol as extraction solution，using HPLC for the determination of liquiritin and glycyrrhizic acid simultaneously，using UV spectrophotometry for determinination the content of total flavonoid,the relationship between the content of liquiritin with glycyrrhizic acid and total flavonoids in Licoric were studied.The data of liquiritin，glycyrrhizic acid and total flavonoids about 60 batches of Licoric was analysized.The results showed that the ratio between the content of glycyrrhiza flavonoids and licorice glycoside to the content of glycyrrhizin in Licorice was in line with the power function significantly；the ratio between the content of glycyrrhizic acid and the content of glycyrrhizin in Licorice was in line with the power function.
