title = "Seperation and determination of glycyrrhizic acid and liquiritin in licorice using SPE-RP-HPLC",
abstract = "Glycyrrhizic acid (GA) and liquiritin are the two classes of bioactive components in licorice with known pharmacological effects. In our stud, different methods were compared to separate GA an- d liquiritin. Solid-phase extraction (SPE) method was verified to separate GA and liquiritin effectively. The method is fast, easy, reliable, and inexpensive; especially in the quality control. Moreover, we built a new method to determine Glycyrrhizic acid and liquiritin simultaneously using reversed phase high performance liquid chromatography (RP-HPLC) In the HPLC analyze, gradient elution and two wavelength were used . The regression line for GA was y =15340.6x+12.81, the regression for liquiritin line was y =9269.1x+20.63, The recovery rates were 101.3\% and 99.4\%; RSD were 1.01\% and 0.92\%.",
