Study by absorption and emission spectrophotometry of the efficiency of the binary mixture (Ethanol-Water) on the extraction of betanin from red beetroot

In this paper, we intend to present a classical method of extraction and analysis betanin from Algerian red beetroot, know the efficiency binary mixture (Ethanol-Water) on extraction. Also, content extract obtained using optical spectroscopic methods. This dye is natural pigment with high antioxidant power widely used as dye. addition, bioavailability reinforces its potential for future therapeutic applications. However, commercially beet extracts never exceeds 1,2% molecule does not exist marketed in more purified form, therefore it necessary have efficient tools enrichment extracts. The experimental results made our laboratory, confirm effectiveness yield extracted beetroot 0,342 mg/g, when solvents large quantity water. As well as, has an absorption band varying 480 nm 540 emission at 800 nm.
