Polydatin is a natural active ingredient extracted from the rhizome and other parts of the Polygonum cuspidatum plant (Polygonaceae family). Its chemical name is 3,4'-5-trihydroxystilbene-3-β-D-glucoside, CAS number 65914-17-2, and molecular formula C20H22O8. It appears as a white needle-like crystalline powder and possesses pharmacological effects such as antitussive, antibacterial, lipid-regulating, and antioxidant properties. Clinically, it is used for cardiovascular diseases and anti-shock treatment. Other names include spruce neoglycoside and resveratrol glycoside.

Protecting Active Ingredients and Promoting Slow-Release and Controlled Release:The porous structure of silica encapsulates active substances such as bamboo leaf flavonoids within its nanopores, isolating them from the effects of oxygen, light, and high temperatures, significantly extending their shelf life. Its controllable pore size and surface chemistry allow for targeted release of active ingredients under specific environmental conditions (such as intestinal pH).
Synergistic Antioxidant and Antibacterial Properties:The antioxidant capacity of bamboo leaf flavonoids synergistically works with the adsorption properties of silica to efficiently scavenge free radicals and adsorb harmful substances. Nano-silica itself possesses certain antibacterial properties; combined with the antibacterial components of bamboo leaf extract, it enhances the inhibitory effect against various microorganisms.
Improving Product Stability and Dispersibility:The complex prevents bamboo leaf extract from precipitating due to aggregation in liquids or pastes, maintaining the homogeneity and stability of the system. Its good flowability and dispersibility facilitate processing and use in various formulations, improving the quality of the final product.
Functional Foods and Cholesterol-Lowering Products: As food additives (such as margarine, dairy products, and beverages), they are used to reduce dietary cholesterol absorption, complying with health claim regulations. They are also formulated into capsules or tablets as lipid-lowering dietary supplements, suitable for the adjunctive management of hypercholesterolemia.
Skincare Products and Topical Preparations: Added to anti-aging and soothing repair skincare products, utilizing their antioxidant and anti-inflammatory properties to protect the skin barrier. Used in ointments or lotions to relieve skin problems such as eczema and dermatitis.
Pharmaceutical and Industrial Applications: Used as pharmaceutical excipients to improve the bioavailability of fat-soluble drugs. Used as a natural emulsifying stabilizer in the cosmetics industry. Used in animal feed to improve lipid metabolism and health status in livestock and poultry.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
