| Summary: | Acorus calamus L., known for diverse therapeutic applications, was studied for its volatile components, antibacterial and antioxidant potential in essential oils from Sabah, Malaysia. Employing hydrodistillation with a Clevenger apparatus, the oils were analysed through gas chromatography-mass spectrometry. Antibacterial activity was assessed via disc diffusion against methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli. Antioxidant properties were evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays. Both leaf and rhizome oils were rich in phenylpropanoids, oxygenated sesquiterpenes, and sesquiterpenes including α-asarone, γ-asarone, methyl isoeugenol, 6-epi�shyobunone, and (E)-β-farnesene. They demonstrated significant antibacterial activity at 400 µg/mL, while displaying lower DPPH (IC50 = 28.20 ± 4.99 µg/mL) and excelling in the FRAP (150.12 ± 0.10 mg TE/g). This ongoing phytochemical analysis of A. calamus holds promise for enhancing quality control, ensuring safety, and validating its traditional applications. |
