Claims
- 1. 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 80-100° 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 80-100° 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.
- 2. The process of claim 1, wherein in step (a) the first solvent and the sample are combined in a proportion of about 8 ml of first solvent per gram of sample.
- 3. The process of claim 1, wherein in step (c) the water and the first ginseng residue are combined in a proportion of about 8 ml of water per gram of ginseng residue.
- 4. The process of claim 1, wherein in step (a) the first ginseng solution is heated for a time period of about 3 hours.
- 5. The process of claim 1, wherein in step (c) the ginseng residue solution is heated for a time period of about 3 hours.
- 6. The process of claim 1, wherein the alcohol solution in the first solvent comprises ethanol or methanol.
- 7. Ginseng fraction CVT-E002, produced according to the process of claim 1.
- 8. A ginseng fraction, having a carbohydrate content which comprises about 0.5-5 mol % rhamnose, about 11-22 mol % galacturonic acid, about 40-60 mol % glucose, about 10-19 mol % galactose and about 11-19 mol % arabinose.
- 9. The ginseng fraction of claim 8, wherein the carbohydrate content comprises about 1-3 mol % rhamnose, about 13-20 mol % galacturonic acid, about 42-57 mol % glucose, about 12-17 mol % galactose and about 13-17 mol % arabinose.
