Chemical characterization of Spathodea campanulata for natural dye

Abstract

Spathodea campanulata a perennial tree identified the potential source of natural dye obtained from the flower at forest college and research institute, mettupalayam during 2016-2017. Spathodea campanulata produces a flower dye that has a wide variety of uses like antimicrobial, anti-fungal, antitumor, etc. So the natural dye extracted from African tulip flowers is found to be environmentally friendly and medical value in nature. To identify various components, the dye is analyzed through Gas chromatography and Mass spectroscopy (GC-MS) using the extract prepared from Soxhlet apparatus using methanol. The following compounds were identified in GCMS analysis, Pectinose Beta-GALACTOSIDASE (yellow), 1-Hexadecanol (Cetyl alcohol), Dodecane (substitute for kerosene fuel), Methyl stearate (ester). The spectrum of the unknown component was compared with the spectrum of the known components stored in the inbuilt library. The extraction of dye from Spathodea campanulata can be done easily and a wide spectrum color range is also available which will be helpful to replace the synthetic dyes. This study may give information on the possible production of natural dyestuff components on a large scale as a source of natural dye.
