Microwave-assisted natural deep eutectic solvents pretreatment followed by hydrodistillation coupled with gc-ms for analysis of essential oil from turmeric (Curcuma longa l.)

What if the secret to a better, greener essential oil was hiding in a simple mix of choline chloride and oxalic acid? A new study shows how this natural deep eutectic solvent, powered by microwaves, unlocks the aromatic potential of turmeric.

This isn't just about getting more oil. It's about doing it sustainably. By pairing NADES with MAHD, the study presents an eco-friendly extraction pathway that reduces reliance on hazardous solvents and energy-intensive methods. It's a promising step forward for quality control and monitoring in the spice industry, proving that green chemistry can be both effective and precise.

Key Points

• NADES pretreatment boosts turmeric essential oil yield.
• Optimized MAHD achieves 0.85% oil yield.
• Green method identifies 49 compounds via GC-MS.
