Abstract: Extraction of pigment from flower with microwave assisted extraction (MAE) technic was investigated in this research in order to obtain an optimal condition under parameters varied. Rosa-damascena was studied as red color pigment source with applying ascorbic acid solution as solvent. For experiment, anthocyanin from Rosa-damascena was extracted under various parameter conditions which are inclusive of temperature (30º C to 80 º C), solvent : solid ratio (10:1 to 30:1), time (5 min to 25 min), energy added (300 W to 1200 W). Then, UV-Visible spectrophotometer has been used for anthocyanin concentration determination. Color appearance has been proved by colorimeter, showing CIE L a* b* hº values
