title: [Fermentation transformed ginsenoside by Lactobacillus plantarum].
abstract: OBJECTIVE
  To explore ginseng fermentation process by Lactobacillus plantarum, and to make part of total saponins transformed into more reactive ginsenoside Rd.
  
  
  METHODS
  Microbial fermentation was carried out by still dark culture. Total saponins were extracted by Soxhlet extraction, and determined by UV visible spectrophotometry with colours reaction by vanillin-sulfuric acid. Ginsenoside Rd was determined by HPLC method.
  
  
  RESULTS
  The fermentation process was: MRS medium, 35 degrees C, pH 5.0, cultured for 2 days. The content of total saponins was inhance 32%, and the content of ginsenoside Rd was increased 4.864 mg x g(-1).
  
  
  CONCLUSIONS
  The fermentation system's process was reasonable, and it's suitable for mass production, important significance for ginsenoside microbial transformation.
