Ngoc Linh ginseng is a Vietnamese endemic ginseng with the
scientific name Panax vietnamensis Ha et Grushv. Since discovered in
1973, it can be said that Ngoc Linh ginseng is one of the most important
medicinal plants. Many reports indicated that Ngoc Linh ginseng has not
only the pharmacological characteristics of a Ginseng, but also the
individual characteristics such as anti-stress, decrease of depression and
anxiety, stimulation of the immune system, resistance to cytotoxic toxins,
antioxidant in vitro and in vivo, etc. The success of propagation of Ngoc
Linh ginseng is still limited because this species is only grown on Ngoc
Linh mountain. To harvest gingseng roots, the propagation period lasts 6 to
7 years to store enough bioactivities. Our thesis entitled “Regeneration and
micropropagation of Ngoc Linh ginseng (Panax vietnamensis Ha et
Grushv.) using thin cell layer technique” has been carried out. The aim of
this study is to obtain a number of vigorous plantlets with and high quality
roots and tubers, especially, they are well adapted to the natural conditions,
thereby contributing to preserving this precious medicinal plant.
