ABSTRACT

Objective:

To develop an HPLC-DAD method for the simultaneous determination of five active flavonoids (quercetin, kaempferol, apigenin, 3-methoxyl-quercetin, nobiletin) in Centipeda minima (L.) A.Br.et Aschers.

Methods:

The chromatographic separation was performed on a Diamonsil C18 column (200 mm×4.6 mm,5 μm) with the mobile phase of 0.1% phosphoric acid-acetonitrile with gradient elution at the flow rate of 0.8 ml·min-1.The detection wavelength was set at 360nm,and the column temperature was maintained at 30 ℃.

Results:

Quercetin, kaempferol, 3-methoxyl-quercetin, apigenin and nobiletin was linear within the range of 0.002 3-0.093 0 μg·μl-1(r=0.999 5) , 0.002 2-0.087 0 μg·μl-1(r=0.999 6),0.002 0-0.079 0 μg·μl-1(r=0.999 8), 0.000 9-0.037 0 μg·μl-1(r=0.999 8) and 0.000 8-0.031 0 μg·μl-1 (r=0.999 9), respectively.The average recovery was 97.66%(RSD=1.17%), 98.33%(RSD=1.16%), 98.63%(RSD=1.10%), 98.40%(RSD=1.52%) and 98.10%(RSD=1.36%)(n=6) , respectively.

Conclusion:

The method is convenient, accurate and reproducible, which can be used for the quality control of Centipeda minima (L.) A.Br.et Aschers.
