method for simplisia extraction were maceration. Catechins were used as
comparison. Quantitative analysis by spectrophotometer obtained maximum
wavelength of catechin 222,00 nm. Catechin standard curve was y = 0.04943x +
0.06692, the value of r = 0.9995. The results showed that tannin content in tea
bag with brand A (0,0092065%), B (0,0091054%), C (0,0086400%), D (0,0076690%),
