Abstract

Polyphenols in tea or often referred to as catechins are different substances with catechins contained in other plants. Catechins in tea do not adversely affect the digestion of food. Tea catechins are antimicrobial (bacteria and viruses), antioxidants, antiradiate, strengthen blood vessels, launch secretions and inhibit cancer cell growth. Catechins are a major group of green tea substances and most influential on all components of tea. In this experiment aims to determine the levels of polyphenols contained in tea premium tea brands tambek by Spektofotometric method using Visible Spectrophotometry. The wavelength used is 725 nm as the wavelength to analyze the polyphenol content in the solution because at this wavelength the absorbance of the rays has the maximum value. The result of the polyphenol experiment of premium tea sample is 80,443 concentration; 122,509; 224,908; 337,269; 484,871; 490; 221; And 553,506 (ppm). Keywords :Pholiphenol, SpectrophotometryVisible
