When I work and study, I always feel that my attention is not concentrated, my memory is obviously decreased, and even symptoms such as dizziness, limb weakness, etc., are caused by overuse of the brain. Long-term use of excessive brain carelessness adjustment may induce neurasthenia, insomnia and other diseases, so as a mental worker must pay attention to the scientific use of the brain, but also pay attention to the brain to timely nutrition. When you think that the brain is running slowly, these foods are the "nutritionals" of your brain. Pine nuts The pine nuts are also known as the "longevity fruit," and have been highly respected by medical doctors and nutrition scholars. This is inseparable from its unique health care function and nutritional value, and is particularly suitable for consumption by people with excessive brain mass. Unsaturated fatty acids contained in pine nuts have the effect of enhancing brain cell metabolism and maintaining brain cell function and neurological function. Glutamate content as high as 16.3%, glutamate has a good brain effect, can enhance memory. In addition, the content of phosphorus and manganese in pine nuts is also very rich, which has a good tonic effect on the brain and nerves, is a brain tonic for mental workers, and also has a good preventive effect on Alzheimer's disease. Although pine nuts are good, it is not for everyone. Spleen deficiency and diarrhea and many patients are best kept away from pine nuts. Because pine nuts are oily and are high in calorie foods (per 100 grams of pine nuts can convert nearly 700 kcal of calories in the body), eating too much will increase body fat. The amount of pine nuts eaten each day is 20- 30 grams is appropriate. peanut Peanut has high nutritional value. It contains 8 kinds of amino acids and unsaturated fatty acids required by the human body. It has certain medicinal value and health care functions. It contains 7% polyphenols. The antioxidant activity of polyphenolic substances is vitamin E 50. Times can effectively delay aging and increase intelligence. Peanut is rich in pantothenic acid (vitamin B5), and it is also taken together with egg yolk and lecithin contained in soybeans to improve memory. The content of zinc in peanut fruits is generally higher than other oil crops. Zinc can promote the development of children's brain, enhance the memory function of the brain, activate the brain cells of the elderly, delay the premature aging of the human body, and resist aging. The lecithin and brain phospholipids in peanut fruits are important substances needed by the nervous system to retard brain function decline, inhibit platelet aggregation, and prevent cerebral thrombosis. Experiments confirmed that regular consumption of peanuts can improve blood circulation, enhance memory and delay aging. walnut The nutritional value of a pound of walnut is equivalent to 5 pounds of eggs or 9 pounds of milk. The protein in walnuts is very important for the human body, which is very beneficial to the brain. Therefore, people who suffer from dizziness, forgetfulness, and heart palpitations due to high work pressure may wish to try some walnuts. Walnuts can reduce the absorption of cholesterol in the intestines. It is beneficial to arteriosclerosis, hypertension, and coronary heart disease. Walnuts have the effect of warming the lungs and preventing asthma and prevent cell aging. They eat a few walnuts each day, or drink porridge added to walnuts. It can delay aging and moisturize the skin. However, the fat contained in walnuts, although beneficial to the removal of unsaturated fatty acids in cholesterol, but the fat itself has a high calorie, if too much food can not be fully utilized, it will be stored as cholesterol, the result is counterproductive . In general, the weight of walnuts taken every day should be about 20 to 40 grams, about the equivalent of 4 to 5 walnuts. fish It is often said that eating fish is smart because the DHA (docosahexaenoic acid) contained in fish is a key element of brain supplementation. They are mainly found in the brain, retina and nerves in the human body. DHA can maintain the normal function of the retina, infants in particular need such nutrients, and promote healthy vision development. DHA is also of great help to human brain development and intelligent development, and it is also an indispensable nutrient for the growth of the nervous system. A new study by the University of Oxford in the UK found that children often eat fish and nuts and they do well. The higher the level of omega 3 fatty acids (especially DHA) in children's blood, the better children's reading ability and memory, and the lower the risk of behavior problems. The main food sources of omega 3 fatty acids include sardines, salmon, salmon, tuna, and other deep-sea fish, flaxseeds, and walnuts. Kiwi The kiwifruit is known as the "King of Fruits" and has an average vitamin C content of 168.9 mg per kiwifruit. As a beauty-loving woman, it knows that vitamin C and vitamin E contained in kiwifruit can be beautiful, anti-oxidant, effectively whiten, and eliminate freckles and acne. And enhance the anti-aging ability of the skin. Actually, kiwi fruit has a strong brain effect, and its rich vitamin C can play a role in relieving depression in the process of brain neurotransmitter synthesis. The latest medical research shows that adult depression has a physiological basis and it is related to a lack of brain neurotransmitters. Kiwifruit contains a serum-promoting hormone that stabilizes the mood and calms the mood. In addition, it contains natural inositol, which helps brain activity and therefore helps depressed people to get out of low mood.
Plant extraction process
1. Select plants/medicinal materials. It is nothing more than ancient prescriptions, proven prescriptions, and folk medicinal herbs. At present, common and uncommon medicinal materials have been studied. Most of the time, the amount of medicinal materials has been increased to extract low-isolated components, or medicinal plants have not been studied from Miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.
2. Extract. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (small polarity → large polarity). Daily decoction of medicines is effective, use water and ethanol and other solvents with high polarity. Artemisinin and other boiling methods are not effective, use petroleum ether and other solvents with low polarity. The common medicinal materials, water/alcohol/ether, are presented again, and more compounds can be separated and identified.
3. Separation. This is the most important task. There are dozens of compounds in the solution extracted in the second step. Generally, column chromatography is used, which is what we often call column flushing. The workload is large, boring, and low-tech. A master's degree may do this every day for 2 years of experimentation. As shown in the figure below, the column for separating compounds is as large as 2 meters high and as small as 10 cm. Change the solvent conditions of the mobile phase, change the material of the column, and repeatedly wash the column under different conditions and separation principles to separate the monomer compound.
