Abstract


Katuk leaf capsules generally use as ASI emitters and katuk leaf capsules also contain iron (II) which to prevent aneemia. Reseaerch on the determination of iron content in katuk leaf capsulse with UV-Visible spectrophotometricmethod has been done. The principle of this research is leuched dry katuk leaf capsulse with HCl 6 M. Then performed the determination rate of iron at 510 nm wavelength by way of reacting iron (II) with 1,10-phenantrolin. So that the complex is formed ferroin orange red. Validation of iron (II) ion analysis method in katuk leaf capsulse has fulfilled the validation criteria that is liniearity with r value = 0,9986, limit of detection (LOD) 0,3588µg/mL, limit of quantitation (LOQ) 1,1960µg/mL, iron (II) content in the sample SI 0,0153µg/mL, SII 0,0225µg/mL, and SIII 0,0268µg/mL.
