Anthocyanin Pigment Identification of Batu Local Rose Flower as A Natural Colorant to Replace Harmful Rhodamin B Colorant

  title={Anthocyanin Pigment Identification of Batu Local Rose Flower as A Natural Colorant to Replace Harmful Rhodamin B Colorant},
  author={Elfi Anis Saati},
This study aimed at identifying anthocyanin pigment in local rose petal from Batu. Extraction processes were conducted in fourlevel solvents (aquades-citric acid, aquades-lactic acid, methanol-HCl and Aquades-sulfuric acid). In order to measure the potential amount of anthocyanin pigment, isolation procedure was done with its twice further developers, concentrated HCl: H2O=3:97 and BuOH-HCl (n BuOH: HCl 2N=1:1) resulting in isolate and powdered pigment. The identification of anthocyanin was… Expand
