Objective: To determine gallic acid and quercetin from different parts of Archidendron clypearia

and to provide evidence for the rational development and utilization of A.clypearia. Method: HPLC method was used with Kromosil C18 column (4.6 mm×250 mm

5 μm)

and the mobile phases were acetonitrile and 0.2% phosphoric acid solution with the gradient elution. The flow rate was 1 mL ·min-1 and the detection wavelength was 254 nm. Result: Both of the content of gallic acid and quercetin are highest in the leaves

lower in the new shoot and lowest in the shoot

even quercetin cannot be tested in the shoot. Conclusion: The method can be used to control the quality of Archidendron clypearia. It is simple

accurate

reproducible and suitable for simultaneous determination of two active constituents in Archidendron clypearia.
