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.
