Background : Korea's agriculture has been forced to change due to the decline in agricultural population, the aging of the population and the conclusion of the Convention on Biological Diversity. Thus, agriculture is seeking to develop into a sixth industry. For this reason, it is necessary to find high-function alternative plant resources for health promotion to meet the changes in national needs for agricultural products. The adventitious roots culture of wild mountain ginseng is the raw material of food code that produced by the biotechnology technique. introduced in the culture of the plant, which is the only way to use a raw material of food. Therefore, in order to increase the yield of ginsenoside in adventitious roots culture of wild mountain ginseng, ginsenoside precursor was treated and ginsenoside contents were analyzed.
Methods and Results : In order to investigate effect of precursor treatment on the production of ginsenoside in adventitious roots culture of wild mountain ginseng, 5 g of adventitious roots culture of mountain ginseng were cultured in liquid SH media supplemented with 2 ㎎/l IBA, 3% sucrose for 8 weeks, which was co-cultured with β-sitosterol and Squalene (0.0625 to 1 mM) or without. Determination of 17 ginsenosides contents of each extract was carried out by HPLC. Rb3 was accumulated by only β-sitosterol, also it increased production of total ginsenoside in the cultured ginseng roots at a concentration of 0.125 mM, which was 2.47-fold higher than that in the control (78.13 ㎎/g of extract).
Conclusion : These results are an important to improve the production yield of ginsenoside in adventitious roots culture of wild mountain ginseng, and they provide an opportunity for development of adventitious roots culture of wild mountain ginseng in dietary health supplement and pharmaceutical industries.
