Abstract
|
|
|
|
PPD ginsenosides in ginseng leaf were analyzed to determine effects of either FIR heat or steaming heat treatment. Among the PPD ginsenosides, Rb1, Rc and Rb3 forming four glycoside-attached aglycons were increased as FIR heat temperatures were increased from 60 to , while Rb3 was decreased. In addition, FIR heat treatment was effective to increase Rd forming a three glycoside-attached aglycon. Rg3 and Rh2 were not increased by the FIR heat treatment. In steaming heat treatment, Rb1 was significantly decreased, while Rb2 was increased. Rd was also increased by increased steaming temperature, yet its content was lower than in the FIR heat treatment. However, the steaming heat treatment increased yields of Rg3 and Rh2, which were not observed in the FIR heat treatment. Thus, FIR heat treatment was beneficial to efficient products of Rb1, Rc, Rb3 and Rd. Steaming heat treatment was effective to higher collection of Rb2, Rg3 and Rh2.
