The objective of this study was to produce the rhizome of Curcuma caesia's ultraviolet-visible (UV-VIS) and Fourier transform infrared (FTIR) spectrum profiles. For the proximate analysis, the extracts were examined in both visible and ultraviolet light. The C. caesia crude extracts. Using a Perkin Elmer spectrophotometer, the rhizome was scanned at wavelengths between 200 and 800 nm, revealing the characteristic peaks. A Perkin Elmer spectrophotometer system was used for the FTIR method, which was used to identify the characteristic peak values and their functional groups. The C. caesia UV-VIS profile. The rhizome methanolic extract had absorption values of 0.617, 1.235, and 0.557, respectively, at peaks at 256.00 nm, 288.00 nm, and 330.00 nm. The FTIR range was utilized to distinguish the useful gathering of the bioactive parts in light of various pinnacle values in the locale of infrared radiation. The current study's findings confirm the presence of the pyrocatachol derivative.
