The content of chemical   compounds as antioxidants in tea leaves is phenolic compounds. The main compound content   of tea leaves includes galic acid and chlorogenic acid. Chlorogenic acid is one of the   hydrocinnamic acid groups that are widely found in coffee, tea drinks and also fruits such as   apples, pears, peaches and cherries. Tea leaves on the market are available in various dosage   forms including simplisia tea leaves, tea bags, beverage tea or instant granule powder liquid.   This study aims to determine the level of chlorogenic acid in liquid extract of tea leaves   circulating on the market with a soaking time of 15 minutes at a temperature of 90°C. Analysis   of chlorogenic acid levels in liquid extract of tea leaves using the Uv-Vis spectrophotometry   method. The phytochemical results obtained showed that the liquid extract of tea leaves had a   positive result in containing flavonoid compounds, alkaloids. The determination of chlorogenic   acid levels on 3 green tea leaf samples circulating in the Bogor regional market, showed that   sample A contained 129.120 mg/g, C of 92.560 mg/g and T of 59.013 mg/g. It can be concluded   that sample A contains the highest levels of chlorogenic acid.  Keywords: Green Tea Leaf, Chlorogenic Acid, UV-VIS Spectrophotometry
