초고압 증숙처리가 산삼배양근의 진세노사이드 Rg3와 Rh2의 함량에 미치는 영향

Abstract

This study was performed to enhance contents of low molecular weight ginsenoside Rh2 and Rg₃ using an ultra high pressure and steaming process in wild cultured-Root in wild ginseng. For selective increase in contents of Rg₃ and Rh2 in cultured wild ginseng roots, an ultra high extraction was applied at 500 MPa for 20 min which was followed by steaming process at 90 ℃ for 12 hr. It was revealed that contents of ginsenosides, Rb1, Rb2, Rc and Rd, were decreased with the complex process described above, whereas contents of ginsenoside Rh2 and Rg₃ were increased up to 4.918 mg/g and 6.115 mg/g, respectively. In addition, concentration of benzo[α]pyrene in extracts of the cultured wild ginseng roots treated by the complex process was 0.64 ppm but it was 0.78 ppm when it was treated with the steaming process. From the results, it was strongly suggested that low molecular weight ginsenosides, Rh2 and Rg₃, are converted from Rb1, Rb2, Rc, and Rd which are easily broken down by an ultra high pressure and steaming process. This results indicate that an ultra high pressure and steaming process can selectively increase in contents of Rg₃ and Rh2 in cultured wild ginseng roots and this process might enhance the utilization and values of cultured wild ginseng roots.
