Abstract:	A rich source of compounds with antioxidant effect is the tea, especially the green tea. Antioxidants activities including those contained by the green tea, depend not only on their structural properties, their chemical reactivity to radical peroxy- acids or other active species, for example but they also depend on many factors, such as concentration, temperature, light, substrate type, physical state of the system, as well as the many microorganisms and minerals that act as pro-oxidant or synergists. This study aims to verify a correlation between the image in the consumer’s mind, the image of the brand for a phytotherapeutic product from herbal tea, and its actual quality, particularly by the presence of a suitable antioxidant activity that corresponds to the antioxidant concentration within the necessary components. This correlation was checked with various quality control techniques, including HPLC.
Keywords:	antioxidants, green tea, quality, brand value
