Abstract

The objective of this study was to compare the antioxidant and antibacterial activity of Curcuma caesia rhizome extracts and to characterise its bioactive metabolites by Fourier Transform-Infrared (FTIR) spectroscopy and Gas Chromatography-Mass Spectroscopy (GC-MS). Extracts were prepared using methanol, acetone and ethyl acetate by cold percolation methods. Compared to other extracts, methanol extract discovered to have the greatest antioxidant capacity. Analysis of FTIR spectra of all the extracts of Curcuma caesia shows the existence of several functional groups such as phenol, aldehydes and carboxylic group. But in methanol extract C≡C stretching bond, nitro compound and conjugated aldehyde were also presented. GC-MS extract assessment showed that sesquiterpene and monoterpenes were primarily presented. This research provides an efficient basis for separating the innovative bioactive compound from plant and assessing their effectiveness for antioxidant and antibacterial operations in particular.
