Soy isoflavones have estrogenic and anti estrogenic properties. Has antioxidant properties. It can inhibit the activity of tyrosine protein kinase (PTK). It can inhibit the activity of topoisomerase II. It has the potential to induce programmed cell death, enhance anti-cancer efficacy, and inhibit angiogenesis, making it a promising cancer chemopreventive agent. Its anti-cancer effects and mechanisms have broad application prospects.

Soy isoflavones are generally stored refrigerated between 0 ° C and 10 ° C (in principle, stored in a cool place below 15 ° C), but compared to product transportation, not all products have the same transportation temperature and storage temperature. The temperature for frozen storage is below 0 ° C. Some products may temporarily heat up during transportation, and for some products with special requirements, we will transport them refrigerated.

Shanghai Tongtian Biotechnology Co., Ltd. is located in Zhangjiang Science and Technology Park, Shanghai, with a total investment of RMB 60 million. Its predecessor was Shenzhen Tongtian Biochemical Technology Co., Ltd., established in February 1999. The company has passed the ISO9001:2000 quality system certification and was recognized as a high-tech enterprise in Shanghai in 2008. The company is committed to the research, development, production, and sales of high-speed countercurrent chromatography (HSCCC), preparative chromatography, medium pressure constant flow pumps, medium pressure plunger pumps, preparative chromatography pumps, medium pressure chromatography systems, and traditional Chinese medicine standard reference materials.

The company has strong research and development capabilities, advanced separation and purification facilities, and complete detection methods, and has achieved results in the development of natural products. The company has successfully extracted the active ingredients of thousands of natural products using high-speed countercurrent chromatography technology, with a purity of over 98%. Among them, more than 3000 monomers and some raw materials have been mass-produced and sold externally, and the company has the ability to develop new products in natural products according to user needs. In terms of industrial development of high-speed countercurrent chromatography application technology, the company has built a production line for huperzine A raw material and put it into use, with an annual production capacity of 20 kilograms, and can expand production scale according to market demand.
