In addition, the benzene ring and heterocyclic structure of 8-hydroxy isoflavones can participate in electrophilic substitution reactions. During halogenation, halogen atoms can replace hydrogen atoms on the benzene ring; nitrification reactions can also introduce nitro groups into suitable positions, which lays the foundation for the synthesis of its derivatives and the expansion of its application range.
In short, the unique chemical properties of 8-hydroxy isoflavones make it a natural compound worthy of further investigation in the fields of medicine, food, and cosmetics.

8-Hydroxyisoflavone is useful in many fields. In the field of medicine, it has significant pharmacological effects. 8-Hydroxyisoflavone can regulate human hormone levels and is quite effective in the prevention and treatment of estrogen-related diseases. Such as female menopause syndrome, which often causes all kinds of discomfort due to fluctuations in estrogen levels, 8-Hydroxyisoflavone can simulate the action of estrogen, relieve hot flashes, night sweats, upset and other diseases, and help women get through this special period smoothly. And it has also made a name for itself in anti-tumor, can induce tumor cell apoptosis, inhibit tumor cell proliferation and metastasis, and provide new ideas for cancer treatment.
In the food field, 8-hydroxy isoflavones can be used as natural antioxidants. Nowadays, food preservation and quality maintenance have attracted much attention, and chemical synthesis of antioxidants may have safety concerns, while 8-hydroxy isoflavones are derived from nature and have high safety. It can effectively remove free radicals in food, delay oxidative deterioration of food, prolong the shelf life of food, and does not affect the flavor and nutritional composition of food, so it can be widely used in various processed foods and beverages.
In the field of cosmetics, 8-hydroxy isoflavones are also useful. Skin aging is a concern for many beauty lovers, and free radical damage is one of the main causes of skin aging. With its antioxidant properties, 8-hydroxyisoflavones can resist the damage of free radicals to skin cells, reduce wrinkle formation, improve skin elasticity and luster, and achieve the effect of beauty and beauty. Many skin care products have included it as an ingredient and are favored by consumers.
In the agricultural field, 8-hydroxyisoflavones have a regulatory effect on plant growth. It can affect the balance of plant hormones, promote plant root development, and enhance plant resistance to adversity. Under harsh environments such as drought and salinity, plants treated with 8-hydroxyisoflavones can often maintain a good growth state, improve crop yield and quality, and have great application potential in modern agricultural production.

There are various ways to synthesize 8-hydroxy isoflavones.
One is to use natural products as starting materials to extract and transform. In the past, many families have found ingredients rich in these similar structures in plants, such as some legumes. First, the relevant natural compounds are carefully extracted, and then the structure is gradually transformed into 8-hydroxy isoflavones through ingenious chemical reactions, such as hydrolysis, oxidation, and rearrangement. The advantage of this approach is that the starting materials are natural or have unique biological activities, but the disadvantages are also obvious. The acquisition of raw materials is limited by time and origin, and the extraction and transformation steps are often complicated, and the yield is difficult to say high.
The second is the method of chemical synthesis. Using common simple organic compounds as the cornerstone, target molecules are constructed by the wonderful technology of organic synthesis. Common ones, phenolic compounds and organic acid derivatives are used as starting materials, and the key intermediates can be obtained first through Friedel-Crafts acylation reaction. Then through cyclization, the basic skeleton of isoflavones is cleverly constructed. Then hydroxyl groups are introduced at specific positions, such as through halogenation, nucleophilic substitution and other reaction steps, to precisely obtain 8-hydroxy isoflavones. The advantage of this approach lies in the ease of purchase of raw materials, and the reaction conditions can be adjusted according to demand, which can be prepared on a large scale. However, the synthesis route may be lengthy, and each step of the reaction needs to be carefully controlled to avoid the clump of side reactions and affect the purity and yield of the product.
The third is biosynthesis. With the help of the catalytic ability of microorganisms or enzymes, 8-hydroxyisoflavones are synthesized under mild conditions. Specific microorganisms, such as some bacteria or fungi, have specific enzyme systems in their bodies, which can catalyze the conversion of related substrates into target products. Or isolate and purify specific enzymes to catalyze the reaction of substrates. This way is green and environmentally friendly, the reaction conditions are mild, and the selectivity is very high. However, the preparation cost of microbial culture or enzymes is quite high, and the biological system is complex and difficult to regulate. More research is needed to improve it.

In today's world, there are many opinions on the market price of eight-hydroxyisoflavones, and it is difficult to have a fixed number. Due to the changing market conditions, the supply and demand situation is impermanent, so its price may rise or fall, and it is difficult to predict.
From the perspective of its production source, if the origin is abundant, the raw materials are abundant, the supply is not in short supply, and the price may tend to be flat. However, if natural and man-made disasters cause the raw materials to be rare, difficult to pick, and the supply is sharply reduced, the price will rise. This is the common sense of supply and demand.
Review its uses. Eight-hydroxyisoflavones are widely used in medicine, beauty and other industries. In medicine, it is related to the treatment of diseases; in beauty, it is related to skin care. If various industries prosper, they need to use a lot, and the demand exceeds the supply, and the price will also rise. On the contrary, if the industry is cold, the demand is weak, and the price will decline.
And the state of market competition. Manufacturers compete and use their own means. Or introduce new ones, reduce costs and increase efficiency, and make profits at a low price; or compete for the market with high prices based on high quality and efficiency. The number of manufacturers is fierce competition, and the price may drop; if there are few manufacturers and monopolies, the price will be higher.
And the progress of technology is also the key. If new technologies are released, the extraction and refining method will be better, and the cost will be reduced, the price is expected to be reduced. If research and development lags behind, the process will be conservative, and the cost will not be reduced, and the price will not be reduced.
To sum up, the market price of octa-hydroxy isoflavones is the result of the interaction of various factors such as supply and demand, use, competition, and technology. To know its exact price, it is necessary to carefully observe the market conditions at that time and cannot be generalized.
