  • Patent number: 11499134
    Abstract: A method for culturing ginseng cell with high content of ginsenoside, including inducing ginseng cell line: after disinfected and sliced, ultrasonically treating old mountain ginseng, and culturing the old mountain ginseng in a culture medium; screening the ginseng cell line: choosing a variety of culture mediums and using hormones for cell separation and culture, selecting cell lines with better growth morphology and faster growth, and performing solid subculture and liquid suspension culture; optimizing conversion conditions: using acids to treat the chosen cell lines, and controlling the treatment temperature and treatment time, detecting ginsenosides Rg3 and Rh2 in the dried products, determining an optimal treatment condition according to the highest total amount; large-scale industrial production: according to the optimal treatment condition, performing the liquid suspension culture of the selected cell lines and scaling up the scale of culture to obtain large-scale industrial production of ginseng cell

  • Publication number: 20200239835
    Abstract: A method for isolating and/or culturing cambium stem cells of panax ginseng is disclosed. The method comprises a step of treating tissues containing panax ginseng cambium with a compound of formula I. The present application further relates to cambium stem cells of panax ginseng obtained according to the method and use of such cambium stem cells in preparing a product for a suspension culture of panax ginseng. The method for isolating and/or culturing cambium stem cells of panax ginseng according to the present application can effectively separate the cambium stem cells of the panax ginseng which have unlimited cytodieresis ability and strong anti-adversity ability, can provide a basis for ultra-large volume liquid culture, which can significantly reduce production costs.
