| Abstract:
Korean ginseng (Panax ginseng C.A. Meyer) was tested to demonstrate that production of this plant with a nutritionally important selenium (Se) is possible, making it a functional ginseng with concentrated Se supplement and the Se incorporated into the enriched Korean ginseng occurs in a soluble, metabolically available form. Sequential extraction was used to assess the degree of solubility of Se. Se content of Korean ginseng represented linear accumulation tendencies in proportion to the increase of Na2SeO4 concentration and duration in the nutrient solution. Results from this solubility experiment indicate that the accumulated Se achieves very soluble form, consequently this Se-enriched plant can economically supply 100 % of Se content in it to human. Two-year-old Korean ginseng containing an anticarcinogenic Se compound can be recommended for growth in a hydroponic system. | |
