Extraction of ginsenosides from fresh ginseng roots (Panax ginseng C.A. Meyer) using commercial enzymes and high hydrostatic pressure.

摘要

A combination of high hydrostatic pressure (HHP) and enzymatic hydrolysis (HHP-EH) was applied for the extraction of ginsenosides from fresh ginseng roots (Panax ginseng C.A. Meyer). The highest yield of ginsenosides was obtained by using a mixture of three enzymes (Celluclast + Termamyl + Viscozyme) along with HHP (100 MPa, at 50 degrees C for 12 h) in comparison to control samples (no enzymes, atmosphere pressure, P < 0.05). Total ginsenosides increased by 184 % while Rg1 + Rb1 increased by 273 %. Application of these conditions significantly increased total ginsenosides by 49 % and Rg1 + Rb1 by 103 % compared to HHP treatment alone (P < 0.05). The effect of HHP on increased yield of ginsenosides is likely due in part, to acceleration of enzyme activity. Thus HHP-EH significantly improves the extraction of ginsenosides from fresh ginseng roots
