Abstract:
A process of preparing ginseng fraction CVT-E002, the process comprising:(a) combining American ginseng with a C1-C6 alcohol solution first solvent in a proportion of about 7-9 ml of first solvent per gram of ginseng and heating the resulting solution at a temperature of about 80-100Â° C. for a time period of about 2-4 hours, to produce a first ginseng solution; (b) thereafter separating the first ginseng solution to produce an alcohol/ginseng solution and a first ginseng residue; (c) thereafter combining the first ginseng residue with water in a proportion of about 7-9 ml of water per gram of ginseng residue and heating the ginseng residue at a temperature of 80-100Â° C. for a time period of 2-4 hours, to produce a ginseng residue solution; (d) thereafter separating the ginseng residue solution to produce a second ginseng residue and an aqueous extract solution containing a ginseng extract; and (e) drying or concentrating the aqueous extract solution to produce ginseng fraction CVT-E002.
