Objective:To establish a HPLC method for the determination of catechin in Eucommia ulmoides. Method: The orthogonal test was used to optimize the pretreatment process. RP-HPLC was adopted
on a column of Agilent HC-C18(4.6 mm×250 mm
5 μm)
using the mobile phase of acetonitrile-0.4% phosphoric acid solution (13∶87)
at a flow rate of 1.0 mL·min-1; the detection wavelength was set at 280 nm. Result: Catechin was linear in the range of 9.620-194.0 μg·mL-1(r=0.999 3). The average recovery of catechin was 97.38% with RSD 2.1%. Conclusion: The method is simple
rapid and reliable with good reproduciblity
which can be used for the content determination of catechin in E. ulmoides.
