Background : Cnidium officinale Makino is a perennial herb of the family Umbelliferae, and an important traditional oriental medicinal plant in China, Japan and Korea. Cnidii Rhizoma, the dried rhizome of C. officinale have been used as traditional oriental medicine in Korea. It has been shown that the cnidii rhizomes are used in the treatment of pain, inflammation, menstrual disturbance, and anti-vitamin deficiency disease, and also act as a blood pressure depressant. In this study, we anticipated to establish the mass propagation system of C. officinale, which is a high economic value as medicinal herb, by plant tissue culture to solve the problem of root stocks contamination. Methods and Results : The whole study was carried out in the department of Herbal crop research, Eumseong, RDA. In this study, C. officinale root bud was used as a explant and it was surface sterilized by 1% sodium hypochlorite for 3 minutes, then several times washed with ddH2O. Multiple shoots were induction them on MS, B5, SH media with 0.1 - 2 ㎎/ℓ auxin (NAA, IBA) and cytokine (BA, Zeatin). In this study we obtained, 7.4 multi-shoots per an explant, and the shoot growth was also favorable in the presence of 0.2 ㎎/ℓ Zeatin. Subsequent transfer of these regenerated shoots on 1/2 SH media resulted in root formation. Rooted plantlets were able to grow in soil after a short period of acclimatization. Conclusion : This experiment was comducted to identify the optimal in vitro propagation condition of C. officinale.
