EVALUATION OF THE CHEMICAL STUDIES, ANTIOXIDANT AND ANTIMICROBIAL ACTIVITIES OF EXTRACTS FROM CURCUMA LONGA (TUMERIC)
Abstract
This study investigates the chemical composition, antioxidant activity, and antimicrobial properties of extracts from Curcuma longa (turmeric). Utilizing Gas Chromatography-Mass Spectrometry (GC-MS), we identified a range of bioactive compounds, which revealed a complex phytochemical profile characterized by distinct molecular formulas, weights, retention times, and functional groups. Antioxidant capacity was evaluated using the DPPH radical scavenging assay. The results indicated a significant positive correlation between extract concentration and antioxidant activity, with C. longa demonstrating considerable efficacy although it was less potent than ascorbic acid. Antimicrobial activity was assessed against various bacterial strains, including Escherichia coli, Staphylococcus aureus, Bacillus anthracis, Klebsiella sp, enterococci and pseudomonas. This study highlights the promising antioxidant and antimicrobial properties of C. longa, suggesting its potential applications in medicinal and nutritional fields. Further research is necessary to explore its mechanisms of action and overall efficacy.
