Development and Utilization of Panax quinquefolium

American ginseng (root) can help the lungs clear fire, thirst, anti-fatigue, anti-aging effects. For many years its price has remained high, imported American ginseng needs about 1,000 yuan per kilogram; domestic prices have been hovering around 500 yuan, and supply in short supply. In the process of growing American ginseng, Chinese medicine farmers only studied how to increase the production of American ginseng, but they ignored the development and utilization of American ginseng stems and leaves. It has been determined that the content of active ingredients such as saponins and polysaccharides in American ginseng leaves is as high as 10% or more, which is twice as much as that in American ginseng roots. If in the 4 to 5 year cycle of growth of American ginseng, the active ingredients in the stems and leaves are all extracted, it is equivalent to the content of the effective component of this ginseng root. In other words, in the process of planting American ginseng, because the American ginseng stems and leaves were not developed and used, the produced medicinal ingredients were lost by 1/2. Therefore, I believe that the development and utilization of American ginseng stems and leaves should be promoted. Some specific methods are now described as follows: (1) Harvesting can be carried out on the stems and leaves of the American ginseng during the period of growth. Generally should be before the first frost, American ginseng stems and leaves will be yellow, and lose the manufacturing nutrient function. The method is: Use a sharp sickle to gently cut off the stems and leaves, bundle into small, dry, do not store large piles, so as not to mold and lose its value. (b) Extracting saponin, volatile oil, and polysaccharides Dried and dried American ginseng stems and leaves after harvesting, and sifting through 20 mesh fine sifting. Weigh 30 kg of stem and leaf dry powder, add 50 kg of fresh water, and put it in a recycling pot to boil and recover volatile oil. After a two-hour ceasefire, the immersion fluid was collected and stored for use. In the leaf residue, add fresh water and boil. Repeat this three times. Combine the collected liquids and condense them to 500 ml. Add 1875 ml of 95% ethanol to make the concentration of ethanol in the liquid 75%. Let stand for 24 hours. The precipitate is a polysaccharide. The filtrate is decompressed to recover ethanol, which is then extracted twice with water-saturated n-butanol, and then decompressed or passed through activated carbon and neutral alumina to recover n-butanol as saponin. The medicinal ingredients extracted by this method can be used for manufacturing proprietary Chinese medicines or health foods. (3) Senate leaf tea is rinsed with clear water and the harvested American ginseng leaves are cleaned, veins are removed, dried and dried, and then it is American ginseng leaf tea, which can be bluntly taken at any time, and can also be accompanied by an appropriate amount of green tea, both tea taste and Fitness body. (D) the system of American ginseng leaf powder will be a clean leaf into a fine powder, with warm boiled water, three times a day, each 1 gram. (5) To prepare several varieties of American ginseng leaves, rinse them and put them into white spirits. Soak for a few days and then add distilled spirits. After the colorless and odorless, eat the ginseng leaves. (six) Senate stewed chicken with a white chicken, a few leaves, into the casserole stew, soup to eat meat, for high-end health food. In addition, they can also be prepared with other Chinese herbal medicines, decoction, treatment of various diseases, or cooking into a variety of tonic food, fitness and fitness. We believe that with the development and utilization of American ginseng stems and leaves in the future, American ginseng, a high-end health food, can enter the homes of millions of ordinary people, and at the same time it can add a very substantial economic income to the ginseng farmers.
