Study on Introduction of Germanium into Panax ginseng Cultured Cells via Chemical Vectors

A great quantity of germanium was abounded in wild Panax ginseng during its growing period for decades, and its medical effects were very strong. The content of germanium absorbed and accumulated in Panax ginseng cultured cells was about 8~17 ppm. Chemical vector compounds VA, VB, and VC of free toxicity for cells were prepared, and germanium was introduced into Panax ginseng cultured cells through using these vectors. During a growth period of 28 days, the quantity of germanium introduced via VA, VB, or VC attained upto 2978, 286, and 483 ppm respectively. Abound of germanium in Panax ginseng was a function of mature cells. Superaddition of germanium via vectors was reasonable at the end of logarithm period. Superaddition of germanium in culture had no influence on biosynthesis and accumulation of Panax ginseng saponin.
