title: [Study on fingerprint spectrum of loquat leaf by HPLC].
abstract: OBJECTIVE
  To establish the fingerprint spectrum of Loquat Leaf of Fujian authentic medicinal herbs by HPCE.
  
  
  METHODS
  The HPLC fingerprints of Loquat Leaf were obtained from instrument HP1100. The HPLC separation was performed on a Eclipse XDB-C18 (4.6 mm x 150 mm, 5 microm) analytical column diluted with methanol-l% glacial acetic acid (90:10) at the flow rate of 1.0 ml/min. The temperature of column was room temperature. The UV detection wavelength was 215 nm.
  
  
  RESULTS
  Detected 12 batches samples of different species Lopuat Leaf Fingerprint by the method of HPLC. Eight peaks in the chromatogram were common. All the similarity were above 0.9, the fingerprints integer feature were coincident essentially.
  
  
  CONCLUSIONS
  The method is convenient, quick and exact, and its reproducibility is good. It will be a scientific reference for qualitation identification and quality evaluation of Loquat Leaf.
