Abstract
OBJECTIVE:To explore ginseng fermentation process by Lactobacillus plantarum, and to make part of total saponins transformed into more reactive ginsenoside Rd.
METHOD: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.
RESULT: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).
CONCLUSION:The fermentation system's process was reasonable, and it's suitable for mass production, important significance for ginsenoside microbial transformation.
