Extraction and Phytochemical Screening of Dye from Bracts of Bougainvillea

Abstract

In this research work the extraction and also phytochemical screening of dye from bracts of Bougainvillea Murayama is evaluated by centrifugation at different time intervals. The filtrate which collected from this extraction were evaluated for phytochemical data. The betacyanin is an active part of dye and it is also used in textile industries and food industries. In this study, the solvent extraction was performed to investigate the effects of factors for the extraction dye from the bracts. .The effects of Solid-liquid ratio and extraction time for the extraction of dye from Bougainvillea bracts were evaluated in this research work. This extraction is performed for 1:1, 1:3, 1:5, 1:7, 1:9, and 2:1 SLR ratio. The pH range was selected between 3.5 to 4.5 for the stability of betacyanin. The dye content of SLR 1:5 was then boiled at 30 ⁰C for 10 min., 20min., 30min., 40 min., 50 min. and 60 min. to get  constant values for equilibrium extraction  time. Phytochemical screening of this dye was performed by taking some lab test. Phytochemical screening of this extracts was performed for Terpenoids, Saponins, Phenol, Volatile oils, Tannins, Flavonoids, cardinolides, Phlobatannins, Steroids and Alkaloids. The equilibrium condition was observed after 40 minutes extraction time for this process of extraction. The aqueous medium condition was evaluated for this extraction of dye.
