Abstract:
Objective To study the optimum procedure of extracting ginsenoside from Panax ginseng by super pressure extracting technique (SPET). Methods SPET was used to extract ginsenoside from P. ginseng at the normal temperature. The optimum extracting process was selected by the orthogonal test. The contents of ginsenoside in P. ginseng were determined by UV-spectrophotometry. Results The optimum condition of SPET was as follows: when the solid dissolved in 50% ethanol, ratio of raw P. ginseng (g) and solvent (mL) was 1∶75, the pressure was kept at 500 MPa for 2 min; the high yield of ginsenoside was up to 7.76%. Conclusion SPET has a series of advantages, such as higher efficiency, shorter extracting time, and lower exhausting energy, at the same time, the impurity is little, etc.
