Hypothesis
Can combining natural deep eutectic solvents with supercritical carbon dioxide enhance the extraction of curcuminoids from turmeric?
Conclusion
The study demonstrates that combining NADESs with scCO2 significantly improves curcuminoid yield and biological activity.
Supporting Evidence
- The optimized extraction method yielded 33.35 mg/g of curcuminoids, outperforming traditional methods.
- The extract showed significant antioxidant activity in DPPH and FRAP assays.
- Enzyme inhibition studies indicated effective inhibition of acetylcholinesterase and tyrosinase.
- Toxicity studies revealed a concentration-dependent response in aquatic invertebrates.
Takeaway
This study shows a new way to get more good stuff from turmeric using special green solvents, which is better for the environment.
Methodology
The study used a Box–Behnken statistical design to optimize extraction conditions and evaluated biological activity through various assays.
Limitations
Further research is needed to assess scalability and safety of the extraction process.
