[Determination of six active ingredients in different parts of Belamcanda chinensis and Iris tectorum and their anti-inflammatory activity].

In order to explore the anti-inflammatory activity and active ingredient basis from the leaves of the Belamcanda chinensis and Iris tectorum, we established an HPLC method for simultaneous determination of six anti-inflammatory active ingredient contents in the root of the B. chinensis and I. tectorum as well as their leaves with different dry methods, and the anti-inflammatory effects of the extract were studied by the mouse ear swelling experiment. The HPLC analysis was performed on an Agilent WondaSil© C₁₈-WR(4.6 mm×250 mm，5 μm)，with isocratic elution of acetonitrile-0.1% ortho-phosphoric acid solution at a flow rate of 1. 0 mL·min⁻¹ and the detection was carried out at 265 nm. The chemical compositions of the B. chinensis and I. tectorum are similar but the contents of them are obviously different. Both rhizome and leaf extract of B. chinensis and I. tectorum had inhibitory effects on inflamed mice induced by dimethylbenzene and had anti-inflammatory effects by animal experiment, which could lay the material and active foundation for the development of the non-medicinal parts of the B. chinensis and I. tectorum.
