title: [Study on HPLC fingerprint of 11 Taraxacum species in northeast of China].
abstract: OBJECTIVE
  To study the RP-HPLC fingerprints of 11 plants in the genus Taraxacum for their quality control.
  
  
  METHODS
  The fingerprints were determined using an Agilent 1100 series instrument system. Chromatographic analyses were performed on a Kromasil 100-5 C18 (4.6 mm x 250 mm, 5 microm) analytical column,eluted with methanol and water containing 0.5% acetic acid as the mobile phases in gradient elution at the flow rate of 1.0 mL x min(-1). The detection wavelength was 323 nm. The temperature of column was 35 degrees C. Eleven species of Taraxacum in northeast of China were detected respectively.
  
  
  RESULTS
  Twenty-five common peaks existed in 11 RP-HPLC fingerprints. By comparing the retention time and the on-line UV spectra, peaks No. 10, No. 12, No. 16 and No. 25 were identified as chlorogenic acid, caffeic acid, p-coumaroy acid and luteolin respectively.
  
  
  CONCLUSIONS
  The analytical method with good precision and reproducibility can be useful in the quality control of Taraxacum plants.
