  • To study on the changes in saponins from callus mass by tissue culture, the callus was derived from the petiole of Korean Ginseng (Panax Ginseng C.A. Meyer) and cultivated on Murashige and Skoog's agar medium supplemented with 2.4-dichlorophenoxyacetic acid and kinetin for 8 months. Then, well-grown callus was analyzed for its components estimation. The results obtained are as follows: (1) When saponins isolated from callus mass were chromatographed on a silca gel plate, and determined by the thinchrograph TFG-10, the ratio of Rb, c to Rg(f) in saponins was 2.16 to 1 and Rb, c, d to Re, g (f) was 1 to 1.63, while in the case of saponins from the root of Panax Ginseng grown by soil culture, the ratio of Rb, c to Rg(f) was 1.03 to 1 and the ratio of Rb, c,d to Re, g(f) was 1 to 1.17. (2) Sapogenins were obtained from the hydrolysates of saponins, and determined by thinchrograph TFG-10. The ratio of panaxadiol to panaxatriol in sapogenins from callus saponins was 2.66 to 1, while the ratio of panaxadiol to panaxatriol in sapogenins from ginseng root saponins was 1.86 to 1. From the results above mentioned, we concluded that the relative contents of sapogenins in saponins from callus mass by tissue culture were different from those in saponins from ginseng root by soil culture.

  • This study was conducted to define the effects of light intensity on the amount of saponin and free sugar and the ratio of triol group saponin and diol group saponin (PT/PD) in the leaf of Panax ginseng C.A. Meyer. 4-Year-old ginseng plants were grown under the shadings of different light transmittance rate(LTR) of 5%, 10%, 20% and 30% for 5 months and the leafiets were sampled from 2nd low at late August to determine the amount of saponin and free sugar.-Rd was main ginseuoside in the diol group saponin but in triol group saponin, ginsenoside-Re showed highest value and next was ginsenoside-$Rg_1$ and $Rg_2$ respectively. Up to 20% of light transmittance rate (LTR), the ginseng leaves grown under high light intensity showed an increase in the amount of total saponin and the ratio of PT/PD but the amount of total saponin and the ratio of PT/PD but the amount of total saponin and the ratio of PT/PD was decreased at the ginseng leaves grown under the shading of 30% LTR. The ginseng leaves grown under the shading of 20% LTR showed a significant increase in the amount of glucose and fructose but a significant decrease of sucrose content. A significant positive correlation ($r=0.992$^{**}$) was recognized between the of amount of total saponin and glucose.
