Catechin dosage (as EGCG)

Epigallocatechin gallate (EGCG) is the most abundant and active catechin in green tea (Camellia sinensis), known for its powerful antioxidant, anti-inflammatory, and cell-protective properties.

The dosage of EGCG catechins makes it possible to specifically quantify this molecule in plant extracts, nutraceutical products, cosmetics or functional drinks.

The analysis is carried out by high-performance liquid chromatography (HPLC or UPLC), coupled with UV detection or mass spectrometry (LC-MS), guaranteeing excellent precision even in the presence of other polyphenols.

This dosage is essential for the standardization of green tea extracts, the validation of health claims or the measurement of stability in formulations rich in natural antioxidants.
