Objective: To optimize the extracting technology of liquiritin in glycyrrhiza. Method: The amount of solvent
the extracting time and the extracting frequencies were assayed by orthogonal test with different concentrations of alcohol as the solvent to detect their influences on the extraction rate of liquiritin in glycyrrhiza; liquiritin content was determined by HPLC. Result: The optimum extracting conditions were as follows: 10 times of 70% alcohol
each 3 h with two times. Conclusion: This procedure was efficient; the extraction technology is reasonable and can provide scientific basis for industrialize process.
