  • Publication number: 20220163500
    Abstract: The present disclosure relates to a marker for identifying Korean ginseng cultivars and a method of identifying Korean ginseng cultivars using the same. Specifically, the present disclosure provides a marker for identification of Korean ginseng cultivars, which is obtained by identifying and separating an active ingredient, which is contained only in Korean ginseng cultivars, among non-saponin components. In addition, the present disclosure makes it possible to determine whether a product sold as Korean ginseng is Korean ginseng by separating and purifying the active ingredient without using a conventional molecular biological method.
