Gallate Catechin Extract
| Gallate Catechin Extract
Polyphenols found in tea are more commonly known as flavanols or catechins and comprise 30-40% of the extractable solids of dried green tea leaves. There are 8 catechins in green tea and of those 8 the gallate catechins are;
Catechin gallate (CG)
A number of the catechin polyphenols that are abundant in tea are reputed to have pharmacologically active properties. Within the plant, catechins are purported to be involved in the defence against pathogens, including insects, bacteria, fungi and viruses. Protection against bacterial and viral infection has also been observed against human pathogens as well as a plethora of other heath parameters. Clinical immunology 2010; 137,347-356
Unlike most green tea extracts on the market which focus on selling EGCG, which is the dominant gallate catechin, Plandaí Biotechnology extract, Phytofare® Catechin Complex, utilizes all four gallate catechins so as to benefit from their synergistic qualities as when a single phytochemical is isolated as an ingredient for a nutraceutical or pharmaceutical related product the synergistic activities created by the presence of the whole phytochemical is lost and therefore bioavailability or absorption is reduced.
By ingesting catechins individually, irrespective of the purity, van Amelsvoort et al. demonstrated that the galloyation of the catechins EGCG, ECG, CG and GCG, whilst having higher activities than those catechins without the galloyl moiety (EGC and CG) have reduced their absorption and are the least absorbed.
