As of late, normal colors and shades acquire significance in nourishment and material ventures as a result of their nontoxic and eco-accommodating qualities. Bougainvillea spectabilis flower are wealthy in betalanin shades which can be utilized as a color in sharpened sun-oriented cells, restorative and nourishment applications. The point of this examination was to advance the common shade extraction from the botanical blossom by reaction surface philosophy. Central Composite Design (CCD) of Response Surface Method (RSM) was connected to assess the ideal states of three process factors to be specific mass of botanical blossom (g), time (t) and temperature (ºC) learned at levels. Mass of blossom furthermore, time were found measurably noteworthy simultaneously and connection coefficient (R2) estimation of 0.96 demonstrated that model was all around fitted with the trial esteems. The ideal procedure conditions were observed to be mass of botanical bracts: 2g, contact time: 205mins and extraction temperature: 30ºC with most extreme absorbance. Reaction Surface Method (RSM) was performed well to recognize the ideal levels of extraction process factors and the approval of anticipated model was fitted 98.06% with the exploratory outcomes led at the ideal conditions. Fourier Transform Infrared Spectroscopy was likewise affirmed the nearness of betalanin color by distinguishing the major useful gatherings.
