title: [Cell suspension culture and flavonoids production in Saussurea involucrate].
abstract: OBJECTIVE
  To establish a system of cell suspension culture for Saussurea involucrate.
  
  
  METHODS
  The effects of different factors on cell growth and flavonoids production of S. involucrate were systematically studied including the media, initial pH values of the medium, carbon sources, inoculum quantity, and plant growth substance.
  
  
  RESULTS
  The optimum medium was N6, initial pH values of the medium was 5.8, sucrose concentration was 50 g x L(-1), inoculum quantity was 60-80 g x L(-1) FW. Medium supplemented with BA (0.5 mg x L(-1)) and NAA (3 mg x L(-1)) was suitable for cell growth, but medium containing BA (0.2 mg x L(-1)) and NAA (2 mg x L(-1)) was suitable for flavonoids production.
  
  
  CONCLUSIONS
  Cell growth and flavonoids production in the suspention of S. involucrate culture cell should be optimized.
