Abstract EN
The ultrasound-assisted extraction (UAE) was initially applied to extract gallic acid from Suaeda glauca Bge.
using 70% ethanol as extraction solvent.
Temperature, liquid-solid ratio, and extraction time were optimized by response surface methodology (RSM), obtaining maximum levels of gallic acid (6.30 mg·g−1) at 51°C, 19.52 mL·g−1, and 42.68 min, respectively.
The obtained model was statistically significant ( p < 0.0001 ).
The verification experiments at the optimum conditions yielded gallic acid for 6.21 mg·g−1.
Subsequently, under optimal conditions, four ionic liquids were used to extract gallic acid from Suaeda glauca Bge.
The results indicated that the presence of 1-hexyl-3-methylimidazolium chloride allowed increasing the EE of gallic acid up to 8.90 mg·g−1.
This might be interpreted in terms of the molecular interaction between ionic liquid and gallic acid.
The use of ionic liquids involves a stronger gallic acid extraction capacity than conventional organic volatile solvents.
A promising alternative process is proposed for the extraction of gallic acid of Suaeda glauca Bge.
