Effect of Different Acids in the Extraction Procedure of Anthocyanin from Locally Available Banana Bract (Bhimkol) by two Different Conventional Methods

Anthocyanin, a coloured natural pigment possesses many phytochemical activities along with various health benefits, so can be used as colourant in food and as drug in pharmaceutical industry. In this study anthocyanin was extracted from flower bracts of ‘Bhimkol’, confirmed by TLC and coloured tests; TAC (Total Anthocyanin Content) was determined using pH-differential method and calculated by using UV-Visible Spectrophotometer under different extraction conditions. The findings of the study reveals that TAC is found to be 40.35 mg/100g in the studied flower bracts using 50% ethanol acidified with 3% citric acid, a naturally occurring antioxidant. The extraction conditions used in this study is mild, avoids degradation of anthocyanin and environmentally benign too. The solvents used are cheap, easily available in common laboratory and can be reused by recovering it using simple distillation technique.
