- Abstract: Background: Melaleuca essential oil has many good effects, bringing economic efficiency; however, low extraction efficiency is a problem that needs to be overcome. This study aims to enhance the efficiency of extracting Melaleuca essential oil by employing deep eutectic solvents (DESs). Materials and methods: Branches and leaves of Melaleuca cajuputi Powell were pretreated by DESs. Carry out the distillation of essential oils by steam distillation. Determination of the chemical composition of essential oils by chromatography-mass spectrometry (GC-MS). Results: The combination of choline chloride and oxalic acid to create DESs solvent system helps the extraction efficiency of Melaleuca essential oil increase by 160%. In addition, the total content of 1,8-cineol and isocineol in the essential oil extracted with DESs solvent was 34.019%, higher than that of the essential oil extracted with distilled water at 30.749%. Conclusions: The positive results show the potential of using DESs solvents to improve the yield and quality of Melaleuca essential oil
