"SUNALPHA" is a formulation of green tea components(mainlytheanineand poiyphenos), ther amino acids and vitamins. Theanine is a unique amino acid and is found only in green tea which gives specific umami tatste Recently, it has been reported that theanine has various biological functions : for example, it acts as an antagonist of caffeine in this study, we determined the relaxation effect of "SUNALPHA" on human volunteers with low anwiety levels by determining the genration of α-waves(a brain wave, 8~13Hz), which is a bio-marker of the relaxed state in human, "SUNALPHA" was administered orally to human volunteers (aged 18 to 22) at the dose of 450 mg in 100ml of water. The mental condition of volunteers was estimated by montoring the emission of brain waves in a closed room with 40 lux of luminows intensity, at 25℃. Volunteers were administered either a blank (water) or a test solution of "SUNALPHA" . Then, emission of α-brian waves was measured for one hour by attaching electrodes to their heads. In the topographic mapping, it could be observed that α-wares were dominant in the occiptal area and spreaded toward the frontal area only in those volunteers who were given the test solution of "SUNALPHA" . Most of the volunteers, 75% showed the same tendency due to an in crease of the emission of the α-brain waves. From this results, it can be suggested that "SUNALPHA" promotes the generation of α-waves in the brain, giving asense of relaxation to the body. As the industrial production of "SUNALPHA" has been achieved, this attractive formulation could be an excellent food additive to make stressed people relax by generationg α-brain waves.
