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 specifi c 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℃ relative to the levels in the control roots that were treated in the dark or at 4℃ for 7 d. Ginseng roots were exposed to LEDs with four different peak emission wavelengths, 380, 450, 470, and 660 ㎚, in closed compartments. Compared with the control 4℃-treated roots, roots that were treated with 450 and 470 ㎚ light showed a signifi cantly increased production of ginsenosides (p＜0.05), with increases of 64.9% and 74.1%, respectively. The contents of the ginsenosides Rb2, Rc, and Rg₁ were signifi cantly higher (p＜0.05) in the 450 and 470 ㎚-treated root samples. The ratio of protopanaxadiol ginsenosides (Rb₁, Rb₂, Rc, and Rd) to protopanaxatriol ginsenosides (Rg₁, Rg₂, Re, and Rf) was signifi cantly higher (p＜0.05) in the 450 and 470 ㎚-treated root samples than in the control 4℃-treated roots. This is the fi rst report that demonstrates the increase and conversion of ginsenosides in raw ginseng roots in response to exposure to LED light.
