about theabrownin

Tea Pigment (aka TP), firstly invented in 1959, is the general designation for the water-soluble colored substances within tea. Its major compositions are theabrownin (TB), theaflavins (TFs) and thearubigins (TRs).

Theabrownin(aka TB) is a prospective tea extract with various strategic biology functions as well as the highest safety among current tea extracts on the market, which is extremely suitable for developing functional food and health care product,even pharmaceuticals.

TB appears as brown powders at room temperature, easily dissolves in water and ethanol.

Until now, the chemical component of TB remains unclear.茗褐生物（Theabio,China) achieved the best theabrownin and QC by fingerprint-like tech.

The major application prospects of TB are
1.Hypolipidemic, particularly in mitigating LDL (Low Density Lipoprotein) like statin.
2.Assist in antidiabetic.
3.Improve the bloodoxygen-carrying capacity.
4.Support in reducing side effect of Chemotherapy by raising Leukocyte level above health threshold.
5.Remove speckles, both for oral and external use.

Our application density ranges from 0.1mg/ml to 8 mg/ml, with 50mg-4g ADI (acceptable daily intake).
The toxicology experiment shows that TB’s LD 50 is much higher than that of tea polyphenol
