title: [Chemical stability of Salvia miltirrhiza hairy root].
abstract: OBJECTIVE
  To study on the chemical stability of Salvia miltirrhiza hairy root.
  
  
  METHODS
  The rolA gene was detected by PCR in DNA and the chemical contituent variances were detected by HPLC.
  
  
  RESULTS
  The rolA gene was found in all the 10 batches of the culfured hairy root. The similarities of the chromatographic fingerprints of the 10 batches are higher than 0. 95.
  
  
  CONCLUSIONS
  There are no significant differences of the chemical constituents in 10 hairy root samples.
