Chemical structures and HPLC chromatograms. A: Chemical structures of six marker components of A. capillaris. B: Representative HPLC chromatogram of reference standards. C: Representative HPLC chromatogram of A. capillaris extract. The detection wavelength was set at 254 nm (I) for hyperoside (3) and isoquercitrin (4), at 320 nm (II) for chlorogenic acid (1), caffeic acid (2), and isochlorogenic acid A (5) and at 340 nm (III) for scoparone (6).
