Abstract

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 (nBuOH: HCl 2N=1:1) resulting in isolate and powdered pigment. The identification of anthocyanin was further conducted by using UV Vis spectrophotometry and FTIR analysis (by malvidin chloride standard). The study result showed that the use of aquades-citric acid and aquades-lactic acid triggered the most apparent anthocyanin pigment identification, as observed by their peak absorbency scale of 0.408 and 0.679 at 513.5-514 nm. The anthocyanin types identified by utilizing spectrophotometry and FTIR analyzes were malvidin glycoside, sianidin glucoside, and pelargonidin glycoside
