Sustainable isolation of ginger (Zingiber officinale) herbal dust bioactive compounds with favorable toxicological profile employing natural deep eutectic solvents (NADES)

The usage of ginger (Zingiber officinale) has increased in recent years due to its positive effect on human health affiliated with its richness in gingerols and shogaols. This study optimized the Ultrasound-assisted extraction (UAE) for better phenolic compounds isolation from ginger herbal dust (GHD), a filter tea industry by-product. The extraction was performed using raw and defatted GHD-previously processed by Supercritical fluid extraction - CO
