Anthocyanin is orange, red, blue and violet pigment. It could be disolved in water and be destroyed by treatment of temperature, pH, O2, light, enzyme and metal. The research objective was to characterize anthocyanin of busy lizzie. In this research, a combination effect of pH and temperature, temperature and heating time, the presence of oxydators, reductor, pigment solubility and condition of storage were studied. This research used a completely randomized design with three replications. The experiment result showed that busy lizzie anthocyanin was stable at pH 3 when it was heated at 40 and 70 degree C, while it was deteriorated at pH 4-5. Heating of anthocyanin at 40 degree C for 30 minutes and 100 degree C for 60 minutes may decreased its absorbtion 45.5 percent and 60.7 percent, respectively. The anthocyanin absorbtion could be preserved 97.7 percent by antioxydant (ascorbic acid). Storage of anthocyanin's extract of busy lizzie at 10 degree C (in refrigerator) for 36 hours could preserved 77.8 percent the absorbtion, while storage at 26-28 degree C could decreased 45.5 percent the absorbtion of anthocyanin's pigment.
