advantage
Stable biological activity
Genistein contains rigid benzene rings and polyhydroxyl groups, with a stable structure, reducing the risk of degradation in the body. The -20℃ low-temperature cold crystallization process is used to protect the integrity of the molecule effectively, and the purity can be stably maintained at more than 98%, ensuring that the biological activity is not affected.
Safe and controllable
Based on advanced metal ion detection technology and microbial limit control, Genistein's lead is strictly controlled to ≤3 ppm, arsenic ≤2 ppm, mercury ≤0.1 ppm, and the total number of microorganisms is ≤1000 cfu/g, ensuring the purity and safety of the product, suitable for medical and functional food applications.
Broad-spectrum antioxidant activity
Based on its polyphenolic hydroxyl structure, Genistein shows excellent antioxidant properties. Through electron spin resonance (ESR) analysis, the product free radical scavenging rate exceeds 85%.
Application
- Medical field: used in the development of anti-cancer drugs, hormone regulators, and osteoporosis prevention and treatment products.
- Healthcare products industry: as a natural phytoestrogen ingredient, it is widely used in nutritional supplements for women's health.
- Cosmetic field: with its antioxidant and anti-aging properties, it is used in anti-aging skin care products.
- Scientific research field: used as experimental research reagents in the fields of tumors, enzyme activity, cell apoptosis, etc.
Storage and transportation
Genistein 446-72-0 should be stored at -20°C, away from light, moisture, and high temperatures to maintain the stability of its chemical structure and biological activity. During transportation, sealed, moisture-proof packaging should be used, and cold chain protection measures should be implemented to ensure that the entire transportation process is kept in a dry, light-proof, and low-temperature environment to prevent product degradation or failure.
