HPLC fingerprint of sunset abelmoschus flower displaying its characteristics and quality was established. Diamonsil 18 chromatog. column (200 mm × 4.6 mm, 5 μm) was adopted, with acetonitrile -0.4% phosphoric acid as mobile phase, gradient elution, flow rate of 1.0 mL/min and detection wavelength of 260 nm. Through anal. of 10 batches of samples, HPLC fingerprint with 17 common peaks, which could distinguish its corol and calyx, was established. Methodol. exploration showed its precision, reproducibility and stability met the requirement. The method is simple, with good reproducibility and strong specificity.
