Figure 1 The high-performance liquid chromatography profiles of the aqueous ethanol (80%) extract of Iris tectorum rhizomes (A) and tectorigenin (B). High-performance liquid chromatography analysis was accomplished at 25 °C on an instrument consisting of L-7110 (Hitachi) pump, L-7420 (Hitachi) ultraviolet detector (set at 254 nm) and Alltech Apollo C18 (4.6 mm × 250 mm) column using MeOH:EtOAc:H2O (60:1:40) mixture as a mobile phase at a flow rate of 1.0 mL/min. Sample injection: 10 μL of extract (2.5 g/L) or tectorigenin (100 mg/L) in MeOH.
