Abstract:

20(S)-Ginsenoside Rg3 and 20(R)-ginsenoside Rg3 were prepared by degradation and extraction methods from leaves of Panax quinquefolium L. The regulation effects of 20(S)-Rg3 and 20(R)-Rg3 on imbalance of Th1/Th2 cell were studied in vivo. As the orthogonal array optimization results shown, when the concentration of acetic acid was 50%, temperature of 80 ℃ and extraction time of 1 h, the conversion rates of 20(S)-Rg3 and 20(R)-Rg3 were highest at 12.30% and 14.80%, respectively. Then the 20(S/R)-Rg3 were purified by chromatographic method. According to the experimental results of activity, 20(S/R)-Rg3 inhibited the Th2 cells development by down-regulation of IL-4 production. It was associated with the CD40 and TIM-4 expression of LDCs. This work reports a new method to prepare ginsenoside Rg3 and draw a novel biological mechanism of ginsenoside Rg3, effects on imbalance of Th1/Th2.

Key words: Degradation, Extraction, 20(S/R)-Ginsenoside Rg3, Th1/Th2 imbalance
