Abstract
An light-emitting diode (LED)-based light source was used as a monochromatic light source to determine the responses of raw ginseng roots (Panax ginseng Meyer) to specific emission spectra with respect to the production of ginsenosides. The ginsenoside content in the ginseng roots changed in response to the LED light treatments at 25 degrees C relative to the levels in the control roots that were treated in the dark or at 4 degrees C for 7 d. Ginseng roots were exposed to LEDs with four different peak emission wavelengths, 380, 450, 470, and 660 nm, in closed compartments. Compared with the control 4 degrees C-treated roots, roots that were treated with 450 and 470 nm light showed a significantly increased production of ginsenosides (p<0.05), with increases of 64.9% and 74.1%, respectively. The contents of the ginsenosides Rb-2, Rc, and Rg(1) were significantly higher (p<0.05) in the 450 and 470 nm-treated root samples. The ratio of protopanaxadiol ginsenosides (Rb-1, Rb-2, Rc, and Rd) to protopanaxatriol ginsenosides (Rg(1), Rg(2), Re, and Rf) was significantly higher (p<0.05) in the 450 and 470 nm-treated root samples than in the control 4 degrees C-treated roots. This is the first report that demonstrates the increase and conversion of ginsenosides in raw ginseng roots in response to exposure to LED light.
