title: [Phenols in seedling cortex of Magnolia officinalis from Enshi].
abstract: OBJECTIVE
  To study the phenols in Cortex of Magnolia officinalis of biernial seedings produced in Enshi, Hubei.
  
  
  METHODS
  The content of magnolol and honokiol in cortexes were determined by HPLC. The chromatograms of 10 samples seedling cortexes were recorded and compared.
  
  
  RESULTS
  The content of magnolol and honokiol in Cortex of Magnolia officinalis of the seedlings from Enshi was higher than other samples. There were ten characteristic absorption bands in the HPLC chromatograms, which differed from the cortex of adult trees.
  
  
  CONCLUSIONS
  The results can be used to identify the quality of the seedlings for the breeding.
