The content of total flavonoids in propolis is the national standard for detecting propolis, and the price of propolis with high flavonoids content will be relatively expensive. Clinical verification shows that propolis with high flavone content has relatively good effect, but the effect of propolis on human body is not only flavone, but also more than 20 kinds and more than 300 elements such as terpenoids, enzymes, trace elements and vitamins. Generally speaking, the quality and safety of propolis (approved by the state) are guaranteed, and it is better to choose propolis with flavonoid content exceeding d%. Generally, concentrated propolis is enough for health care, and it can also be used to treat some diseases, 2 capsules each time, 2-3 times a day. Real propolis has no side effects on human body (a large enterprise with GMP certification). Don't buy crude gelatin without purification, which has side effects on human body.
Total flavonoids refers to the total amount of flavonoids contained in propolis or propolis products, which is generally expressed as "g/100g".
The basic component of propolis is flavonoids. Flavonoids are essential nutrients for human body, which cannot be synthesized in human body and can only be ingested from diet. They are an indispensable class of important substances for life movement and regulation of human physiological functions.
Flavonoids are composed of flavonoids, flavonols, flavanones and other forms, which are derived from plants and are secondary metabolites of plants. Vegetables, fruits and herbs mostly contain flavonoids.
Propolis is one of the natural substances with the highest content of total flavonoids in nature, and its content is tens of thousands to millions of times higher than that of vegetables, fruits and plants. It is an ideal natural flavonoid supplement.
The total flavonoids of propolis are composed of more than 30 flavonoids. Among them, rutin, myricetin, quercetin, camphene, apigenin, squirrel element, galangin and Coyne are the main representatives of total flavonoids in propolis.
In a sense, propolis is famous because it is rich in flavonoids. Whether evaluating propolis from traditional medicine or modern medicine, we can't ignore the important role of flavonoids in propolis. Especially in recent years, with the development of free radical life science, flavonoids with strong antioxidant and free radical scavenging effects have attracted unprecedented attention. Flavonoids participate in the metabolism of phosphoric acid and arachidonic acid, phosphorylation of protein, calcium ion transfer, free radical scavenging, redox, coupling and gene expression. A large number of experiments and clinical trials have proved that the medical functions of flavonoids include anti-inflammatory, anti-allergic, anti-infection, anti-tumor, anti-chemical poison, parasite inhibition, virus inhibition, prevention and treatment of liver diseases, vascular diseases, vascular embolism, cardiovascular and cerebrovascular diseases and so on. It can be seen that the comprehensive efficacy of propolis is almost related to flavonoids.
Question 2: What is flavone? What is the function of flavonoids? In fact, it is a substance extracted from natural plants such as soybean and fern root, which can replace estrogen. Because it can produce physiological effects with more than 400 kinds of tissues in human body, it is not real estrogen, so it will not start nuclear mutation and has no side effects of estrogen. At the same time, it also has a two-way regulation function, which has a resistance effect when estrogen is high in the body and a supplement effect when estrogen is low. Therefore, it has the functions of regulating human endocrine level, eliminating climacteric syndrome, such as irritability, hot flashes, sweating, insomnia, memory loss, and regulating cardiovascular function. Improve skin quality and sexual life quality, prevent osteoporosis, Alzheimer's disease, and resist endometrial cancer and cancer.
However, because everyone's physical condition is different, isoflavones are often used with calcium and vitamins at the same time, so it is best to test the sub-health state to determine the efficacy of supplementing nutrients to assist isoflavones. Because of the lack of knowledge in this field, women buy at will and take it blindly, which is difficult to have practical effect. Therefore, even the best things should be used scientifically.

Question 3: What is the difference between flavonoids and total flavonoids? Propolis contains more than 20 kinds of flavonoids, which are the active substances of propolis, accounting for about 4. 13% of the total propolis. These flavonoids include flavonoids, flavonols and dihydroflavones. Flavonoids include chrysin, chrysin, Robinia pseudoacacia, apigenin, salicin and so on. Flavonoids include galangin, galangin, rhamnetin, isorhamnetin, rhamnetin, kaempferide, betulin, quercetin and their derivatives, and dihydroflavonoids include Yue Se Ning, strobilurin, cherry blossom element, isorhamnetin and naringin. To measure the quality of a propolis product, as long as the content of total flavonoids is identified, the content of total flavonoids in propolis from different products and producing areas is slightly different. Propolis, natural antibiotics, a good helper for diabetes, and a blood vessel cleaner, together with nattokinase, can play a dual role in protecting the heart and brain and prolonging life.
Question 4: What is flavone? Antioxidant and health-care effects of plant flavonoids
In recent years, a new discipline has developed rapidly, which is free radical biomedicine. It has been found that there are nearly 100 kinds of body injuries and diseases related to free radicals, such as arteriosclerosis, hyperlipidemia, tumors and so on. In recent years, the development of free radical biology has penetrated into the field of nutrition and become an important index to evaluate the nutritional value of food. Some authoritative nutritionists in the world also put forward that the nutritional value of food should be evaluated by the antioxidant capacity of food, and the requirement of human nutrients should be determined according to the antioxidant capacity of nutrients in the body, and the research focus should be gradually shifted from vitamins to natural extracts such as plants.
After years of research, scientists have proved that bioflavonoids have many functions, such as anti-atherosclerosis, anti-virus, anti-tumor, anti-inflammatory and anti-allergic. They are widely found in plants in nature. At present, scientists have identified more than 4000 flavonoids with different chemical structures from natural plants. Flavonoids with biochemical activity participate in many biochemical functions in human body, including effectively scavenging free radicals or blocking free radical chain reaction; Protect lipids from pathological peroxide damage; Protect and stabilize vitamin c in the body; Promote the stability of intracellular and extracellular calcium. Among the sources of bioflavonoids, blueberry extract is a representative one. This compound antioxidant is rich in healthy, unique and bioflavonoid acesulfame K. It has many functions in human body, such as scavenging free radicals, improving circulatory system and delaying aging. As we all know, the occurrence of hypertension, hyperlipidemia and arteriosclerosis is closely related to the abnormal increase of harmful free radicals in the circulatory system. When people's food contains a certain amount of vitamin E, the risk of myocardial infarction can be reduced by 40%, because vitamin E has antioxidant effect, and the antioxidant activity of acetum is 50 times that of vitamin E. Western experts conducted epidemiological surveys in seven countries and found that the greater the daily intake of flavonoids, the lower the risk of dying of heart disease. The researchers administered acesulfame K from blueberry to patients with cerebral thrombosis, and found that it significantly improved the antioxidant capacity of lipoprotein and reduced the concentration of cholesterol in blood. This shows that antioxidants can improve the normal metabolism of circulatory system, maintain and promote its function by eliminating the harmful effects of excessive free radicals in cardiovascular system and blood, and have a positive guarantee for the prevention and treatment of some circulatory system diseases.
2 1 century, mankind will make greater achievements in fighting and defeating diseases, among which antioxidants will play an important role in maintaining human health and improving human quality of life, and plant flavonoids with good biological activity extracted from nature will play an increasingly important role in preventing and treating diseases, especially circulatory diseases.
Question 5: What is flavone? What is the flavone in propolis? It is the abbreviation of flavonoids, and there are many kinds. It is an antioxidant existing in nature, which can efficiently remove free radicals, has anti-inflammatory and bactericidal effects, and can improve blood circulation and regulate blood lipids. The main component of propolis is flavonoids, and the so-called total flavonoids in the product refers to the content of flavonoids. Each product has a different label. It should be noted that the flavonoid content of natural propolis is generally between 2-6%. The total flavonoids of many propolis exceed 6%, even 10%, which is actually rutin added.
