Abstract

The present study was aimed to produce the ultraviolet-visible (UV-VIS) and Fourier transform infrared (FTIR)
spectrum profile of Curcuma caesia rhizome. The extracts were examined under visible and UV light for the
proximate analysis. The crude extracts of C. caesia. Rhizome was scanned in the wavelength ranging from
200 nm to 800 nm by using Perkin Elmer spectrophotometer and the characteristic peaks were detected. FTIR
method was performed on a Perkin Elmer spectrophotometer system, which was used to detect the characteristic
peak values and their functional groups. The UV-VIS profile of C. caesia. rhizome methanolic extract showed
the peaks at 256.00 nm, 288.00 nm and 330.00 nm with the absorption 0.617,1.235 and 0.557respectively. The
FTIR spectrum was used to identify the functional group of the bioactive components based on different peak
values in the region of infrared radiation. The results of the present study confirm the presence of pyrocatachol
derivative.
