Identification and Quality Assessment of Chrysanthemum Buds by CE Fingerprinting

Figure 1

Standard fingerprint for chrysanthemum buds obtained from CE with the carbon working electrode. Peak 5: chlorogenic acid; Peak 6: luteolin. Working potential is 0.95 V (versus SCE); running buffer: Na₂B₄O₇-NaOH (pH 11.25, 3.1 × 10⁻³ g mL⁻¹ boric acid ions); separation voltage: 14 kV, inject time: 8 s.
