Optimized green extraction of agarwood essential oil using custom natural deep eutectic solvents: Chemical analysis and bioactivity evaluation

Year: 2024

Type: article

Abstract: This study explores an innovative and environmentally friendly method for extracting essential oils (EOs) from agarwood using custom natural deep eutectic solvents (DESs), specifically a mixture of choline chloride and lactic acid. Traditional water distillation methods often result in lower yields and the degradation of delicate aromatic compounds. In contrast, the DES method significantly enhances the extraction efficiency and quality of agarwood EOs, achieving a yield 2.12 times higher than water distillation. Gas chromatography-mass spectrometry (GC-MS) analysis revealed a richer profile of sesquiterpenes and alkane hydrocarbons in DES-extracted oils, indicating a superior quality product with enhanced antioxidant properties. Scanning electron microscopy (SEM) confirmed that DESs effectively disrupt agarwood cell walls, facilitating a more complete release of aromatic compounds while preserving volatile components. Additionally, DESs are biodegradable and exhibit reduced toxicity, offering a sustainable alternative in the essential oil extraction industry. This research underscores the potential of DES-based extraction techniques as a viable and superior method for producing high-quality agarwood essential oils, with significant implications for sustainable practices in the fragrance and pharmaceutical industries.
