Abstract :
This study aims to determine the ability of ethanol extract of green tea (Camellia sinensis L.) as a heavy metal chelating agent Cu. Green tea (Camellia sinensis L.) was extracted using maceration method with 96% ethanol solvent. The ethanol extract of green tea obtained was tested by phytochemical screening. Analysis of the reduction in total heavy metal content of 10 ppm Cu was measured on an Atomic Absorption Spectrophotometer with a wavelength of 324,8 nm. The ethanol extract of green tea (Camellia sinensis L.) made a series of concentrations of 3 ppm, 6 ppm, 12 ppm and 15 ppm. The results showed ethanol extract of green tea (Camellia sinensis L.) containing alkaloids, flavonoids, phenolics, tannins, saponins and triterpenoids. The average concentration value of ethanol extract of green tea in reducing Cu metal up to 50% (EC50) was 12,2648 ppm with a coefficient of variation of 0,2358%.
