Overview: 
A short description of the available technology.

We have developed a technology, which relates to an enriched extract and single active compound from rooibos tea. This compound has a demonstrable effect against a variety of metabolic disorders, a major worldwide health threat. The SAMRC has generated substantial in vitro and in vivo data on the potential health benefits of the compound and extract and has developed a synthetic method for the production of the active ingredient."

Brief description of the technology’s market need.

Aspalathus linearis, commonly known as rooibos, is well known for its various health properties, some of which include antioxidant and stress-lowering properties. Rooibos is also rich in polyphenols and is the only plant known to contain the phenolic antioxidant, aspalathin. The aspalathin content of the rooibos plant varies depending on a number of factors, and its concentrations within the plant material is diminished during the fermentation process, which is necessary as the oxidation process results in the characteristic red-brown colour and aromatic flavour. Unfermented (green) rooibos, which is not oxidised, contains much higher levels of aspalathin than the fermented rooibos, this product is commonly prepared as a herbal tea.
Metabolic disorders are commonplace and have dire medical consequences, antioxidants may be able to mitigate the development and consequences of metabolic disorders.

Value proposition/benefits: 
Brief description of the technology’s benefits.

The SAMRC and the Agricultural Research Council (ARC) have developed a method for the production of aspalathin-enriched green rooibos extract (GRT Extract), containing a minimum of 12% aspalathin, and having a number of beneficial effects in the management of conditions linked to glucose and lipid metabolism. The beneficial effects of aspalathin and aspalathin-rich green rooibos extracts (ARC2 and Afriplex GRT) are based on current and previous research conducted by the SAMRC and others.
