Objective:To establish a HPLC method for determination of geniposide and liquiritigenin in Legan-Qingyan Capsules.Methods: A Kromasil C18 Column(4.6 mm×250 mm
5 μm)was used.The mobile phase was methanol-0.5% glacial acetic acid
the flow rate was 1.0 mL·min-1
λ1=238 nm(for the geniposide)
λ2=276 nm(for the liquiritigenin)
the column temperature was 30 ℃.Results: The linear range for geniposide was within(54.1~162.4)μg·mL-1
r=0.999 8
recovery was 99.66%(n=9).The linear range for liquiritigenin was within(5.2~15.5)μg·mL-1
r=0.999 9
recovery was 99.90%(n=9).Conclusion:This method has good reproducibility.It can be used for quality control in production of Legan-Qingyan Capsules.
