Objective: To compare the content of liquiritin in Sini traditional decoction
the granules and the ingle-flavor granules. Method :To determine the content of liquiritin by HPLC method Diamonsil C18 column (4.6 mm×150 mm
5 μm)was
used
the mobile phase of acetonitrile-0.1% acetic acid-water(20 ∶80). The flonrate was 0.7 mL·min-1 and the detection wave length was at 276 nm. The tem perature of colcomn was 25 ℃. Result :The content of liquiritin was 31.13 mg in traditional decoction
48.48 mg in the granules and 31.95 mg in the ingle-flavor granules in a prescription. Conclusion :The content of liquiritin is significantly different formulations
which can provide the scientific basis for further research of Sini decoction type.
