Diosmetin(520-34-3)

Diosmetin (CAS: 520-34-3), chemically named 3',5,7-Trihydroxy-4'-methoxyflavone, has the chemical formula C₁₆H₁₂O₆ and a molecular weight of 300.26. It is a naturally occurring flavonoid monomer compound, belonging to the flavonoid family. Named after being first isolated and extracted from Diosma orientalis, it is widely distributed in various medicinal plants and药食同源 plants in nature. Common sources include lemon, mint, rosemary, Diosma orientalis, dried tangerine peel, licorice, etc. As an important secondary metabolite in plants, it has both natural safety and diverse pharmacological activities, and has extremely high application value and research potential in medicine, health products, cosmetics, food and other fields.

In terms of physical and chemical properties, Diosmetin appears as a pale yellow crystalline powder, odorless, tasteless and non-irritating, with stable physical and chemical properties and not easy to decompose and deteriorate. Its solubility has obvious polar characteristics: it is almost insoluble in cold water, slightly soluble in warm water, and easily soluble in organic solvents such as ethanol, methanol, acetone and dimethyl sulfoxide (DMSO). Its solubility will be significantly improved in alkaline solutions. This solubility feature enables it to adapt to the processing needs of different fields. Whether it is the preparation of pharmaceutical preparations, the compounding of cosmetics, or the use of scientific research experiments, it can achieve efficient dissolution through a suitable solvent system. Since it is relatively sensitive to strong light, high temperature and high humidity environments, long-term exposure to such environments is prone to oxidative discoloration and reduced activity. Therefore, it must be stored in sealed, light-proof, dry and low-temperature (2-8℃) conditions to avoid moisture absorption, caking and component inactivation, ensuring the purity and activity stability of the product.

The core advantage of Diosmetin lies in its natural low toxicity, high safety and diverse biological activities. Verified by multiple toxicological experiments, it has no obvious toxic and side effects, no mutagenicity, no damage to normal human cells, and is suitable for long-term use, which also lays a foundation for its wide application in various products. Its core biological activities are concentrated in antioxidant, anti-inflammatory, antibacterial, antiviral, cell protection and other aspects, among which antioxidant and anti-inflammatory activities are the most prominent. As a powerful natural antioxidant, Diosmetin can efficiently scavenge excess reactive oxygen free radicals in the body, inhibit lipid peroxidation, reduce oxidative damage to cells, delay cell aging and tissue degradation, and at the same time enhance the body's own antioxidant capacity, protecting cells from oxidative stress damage. In terms of anti-inflammation, it can effectively inhibit the release of inflammatory factors in the body, block the inflammatory signal transduction pathway, soothe the body's inflammatory response, and has a certain auxiliary improvement effect on various inflammatory diseases, especially suitable for the R&D of products that need anti-inflammatory and soothing effects.

In addition, Diosmetin also has broad-spectrum antibacterial and antiviral activities, which can inhibit the growth and reproduction of various bacteria and viruses, enhance the body's resistance; at the same time, it can regulate the body's metabolic function, promote cell repair, improve cell physiological state, and also has certain potential value in regulating immunity and protecting cardiovascular system. These diverse biological activities enable it to play an important role in many fields and become a high-quality choice among natural functional raw materials.

In terms of production process, Diosmetin is mainly prepared by natural plant extraction method. Using plants rich in this component such as lemon peel, mint and Diosma orientalis as raw materials, high-purity Diosmetin products are obtained through a series of precision processes including crushing, extraction, filtration, purification, crystallization and drying. At present, the production process has reached a high degree of maturity, and the product purity can reach more than 95%-98%, with extremely low impurity content, meeting the usage standards of different fields such as food grade, pharmaceutical grade and cosmetic grade. The production process is green and environmentally friendly, without the production of toxic and harmful substances, which conforms to the development concept of modern green industry. At the same time, the particle size, purity and other indicators of the product can be adjusted by optimizing the process parameters to adapt to the specific usage needs of different industries, further expanding its application scope.

In terms of application scenarios, Diosmetin is widely used in many fields such as pharmaceutical research, health products, functional food and high-end cosmetics. In the field of pharmaceutical research, it is often used as a standard reference substance and pharmacological experimental reagent for the determination of flavonoid content and the study of pharmacodynamic mechanisms. It is also an important lead compound for the R&D of anti-inflammatory, antiviral and antioxidant innovative drugs, providing strong support for pharmaceutical R&D. In the field of health products, it can be used as a natural functional raw material, added to dietary supplements with antioxidant, immune-enhancing and anti-inflammatory effects, to meet people's demand for natural and healthy products. In the field of functional food, it can be used as a natural food additive to improve the nutritional value and functionality of food, adapting to the R&D and production of healthy food. In the field of high-end cosmetics, relying on its antioxidant, anti-inflammatory, soothing and skin-repairing effects, it can be added to anti-aging essences, soothing lotions, repairing creams and other products to improve dull skin, sensitive redness and other problems, and enhance the functionality and user experience of skin care products.

With the popularization of natural health concepts and the rapid development of related industries, the demand for natural, safe and efficient functional raw materials is increasing day by day. As a natural flavonoid monomer, Diosmetin has become a research hotspot in the field of natural active ingredients due to its excellent biological activities, natural safety and wide adaptability. In the future, with the continuous optimization of production processes and the continuous expansion of application scenarios, Diosmetin will play an important role in more fields, and its research value and market potential will be further released, becoming an important core raw material for promoting the development of medicine, health products, cosmetics and other industries.
