Rhoifolin(CAS:17306-46-6)

Rhoifolin (CAS: 17306-46-6), with molecular formula C₂₇H₃₀O₁₄ and molecular weight of 578.52, is a high-value natural flavonoid glycoside. It is mainly derived from natural plants such as osmanthus fragrans, turpinia arguta and toxicodendron succedaneum. As an important secondary metabolite in plants, Rhoifolin has been widely used in high-end cosmetics, biomedicine, scientific research and health products due to its pure natural source, mild safety and excellent biological activities. With stable structure and unique activity, it is different from ordinary flavonoid monomers and has dual value of skin repair and pharmacological conditioning, making it a scarce and popular high-end flavonoid glycoside raw material.

In terms of physical and chemical properties, Rhoifolin appears as yellow crystalline powder with uniform color, no peculiar smell and no irritation. It has stable chemical properties. It is insoluble in cold water, slightly soluble in hot water, and easily soluble in organic solvents such as methanol, ethanol and DMSO. It is compatible with various industrial formula systems. Although it is not easy to deteriorate at room temperature, it is sensitive to strong light and high humidity. Long-term exposure may cause oxidation and color darkening. It should be stored in sealed, light-proof, cool and dry conditions away from oxidants to maintain stable color, purity and activity.

In industrial production, Rhoifolin is extracted from osmanthus fragrans and turpinia arguta through low-temperature green extraction technology. The production procedures include raw material screening, cleaning, low-temperature crushing, ethanol extraction, chromatographic separation, purification, recrystallization and vacuum drying. With macroporous resin enrichment and high-efficiency liquid-phase purification technology, impurities are effectively removed. Industrial refined Rhoifolin can reach a purity of more than 98%, featuring pure color, low impurities and no harmful residues. It meets cosmetic grade and pharmaceutical intermediate standards, suitable for high-end production and precise scientific research.

Rhoifolin has diverse and prominent biological activities, including antioxidant, anti-inflammatory, bacteriostatic and skin-repairing effects. It can efficiently scavenge excess free radicals, inhibit lipid peroxidation and reduce oxidative damage to delay skin aging and dullness. It inhibits the release of inflammatory factors to relieve skin redness, sensitivity and heat discomfort, reducing external skin damage. Its bacteriostatic property restrains the growth of harmful microorganisms and optimizes the skin microecological environment. In addition, Rhoifolin repairs the skin barrier and enhances skin tolerance with mild and low-irritation characteristics, ideal for sensitive skin formulas.

Rhoifolin has a wide range of high-end applications. In the cosmetic industry, it is commonly added into serums, essences, creams and toners for anti-oxidation, brightening, barrier repair and soothing. In the pharmaceutical field, it acts as a pharmaceutical intermediate for the research and development of anti-inflammatory and antioxidant drugs. In scientific research, it is widely used in flavonoid pharmacological experiments. In health products, it can be compounded with other flavonoids to regulate human metabolism and improve antioxidant capacity.

With the rapid development of global natural skin care and green biomedicine industries, pure natural, low-irritation and high-activity plant raw materials have become the mainstream trend. Benefiting from its rare flavonoid glycoside structure, pure yellow powder appearance and high safety, Rhoifolin enjoys continuously growing market demand. In the future, the production cost will be reduced with optimized extraction technology, and water solubility modification will further expand its application scope. With stable quality and multiple functions, Rhoifolin will continue to develop in high-end cosmetics and biomedicine, becoming a promising high-quality natural plant active raw material.
