It has contains chemicals such as cycloartenyl acetate, lupenone, β-sitosterol, taraxerone, octacosanoic acid, and praeruptorin A. Radix Adenophorae considered to be effective regulating humoral and cellular immunity, antimutation, restraining adenocarcinoma cell, strengthening cardiac function, allaying a fever, and easing pain and cough. In this study, we tried to establish a mass production system of A. triphylla which has high economic value as a medicinal herb by plant tissue culture in order to cultivate standard varieties.
Methods and Results : In this study, A. triphylla internode was used as a explant and it was surface sterilized by 1% sodium hypochlorite for 5 minutes, consequently several times washed with ddH2O. Further it was placed in to MS medium including with axillary bud. The 1/2MS, B5, SH was used in this research. And the plant growth regulator of 0.1 - 2 ㎎/ℓ auxins (NAA, IBA) and cytokines (BA) were used respectively to achieve multiple shoots. The whole study was carried out in the department of Herbal crop research, Eumseong, RDA.
Conclusion : In this study we obtained, 6.2 multi-shoots per an explant, and the shoot growth was also favorable in the presence of 1.0 ㎎/ℓ BA and 1.0 ㎎/ℓ IBA.
