Optimization of the culture medium of adventitious root culture to produce the flavonoids and the triterpenoids of Actinidia arguta by using an orthogonal design process

The roots of Actinidia arguta (a berry fruit tree) are used in traditional medicine. However, the inconsistent quality of A. arguta roots affects the extract or the drug produced. The adventitious root (AR) culture technology may be used to ameliorate such problem. Therefore, this study induced A. arguta ARs from the roots of in vitro cultured plantlets, and the optimal culture medium was selected using the L9(34) orthogonal design with four...
