title: [Effects of precursor feeding and fungal elicitors on secondary metabolits in cell suspension culture of Cistanche deserticola].
abstract: OBJECTIVE
  To investigate the effects of precursor feeding and fungal elicitors on cell growth and the contents of PeGs and Echin in the cell supension culture of Cistanche deserticola.
  
  
  METHODS
  The combination of precursor feeding and fungal elicitors were added on the cell suspension culture.
  
  
  RESULTS
  The combination of L-phenylalanine and L-Tyrosing were added with Cladosporium fulvum, the dry weight of cell and the contents of PeGs and Echin in suspention all reached the highest value, 14.69 gDW/L, 50.55 mg/g and 23.86 mg/g, which were 1.81, 4.18 and 3.99 times as much as the values of controls, respectively.
  
  
  CONCLUSIONS
  Precursor feeding and fungal elicitors had obvious promotion effects on cell growth and contents of PeGs and Echin in cell suspension culture of C. deserticola.
