Tauto biotech as a Leader Supplier of Botanical Reference Materials in China, have more than 17 years of history,$9 million in assets,and agents in around 13 countries. We are devoted to the research, production and sales of valid monomer of natural plants with high purity and raw materials/intermediate of Herbal medicines.With the use of HSCCC, we have successfully extracted over 3000 monomers with the purification over 98%. Also we have the ability of manufacturing new products among the herbal extracts at the client's will. 

We have built a product lines to produce Ginkgolic Acid (C15:0) and it's capacity could be more than 20 kilograms a year.CoMPare with the other manufacturers,the cost and the quality of our Ginkgolic Acid (C15:0) should be more ascendant because we have the stable material resource and the patent technology.

The quality is guaranteed as we have certification of ISO 9001:2008 International Quality Systerm. And each product has passed very strict tests (NMR\MS\HPLC).
