| dc.description.abstract | Objective: The aims of the study was to explore the application effect of ionic liquid as a green solvent in the polyphenolics content extraction from Peperomia pellucida (L.) Kunth herbs using 1-butyl-3-methyl imidazolium bromide ([BMIM]Br) and 1-butyl-3-methyl imidazolium chloride ([BMIM]Cl). Methods: The polyphenolics content extraction was performed by using the ionic liquid based microwave-assisted extraction (IL-MAE) method with some extraction parameters, including extraction time, microwave power,
ratio liquid-solid, and ionic liquid concentration. The yields of total polyphenolic content were examined using a microplate reader 96 well method,
and the extraction mechanism was analyzed using scanning electron
microscopy (SEM). Results: The results showed that the effect of ionic liquid
on the yield of total polyphenolics content, including 18.287 µg GAE/g
(0.7 mol/l [BMIM]Cl concentration, 14 ml/l liquid-solid ratio, and 270 Watts
microwave power for 10 minutes), and 15.734 µg GAE/g (0.7 mol/l [BMIM]
Br concentration, 14 ml/l liquid-solid ratio, and 270 Watts microwave power
for 15 minutes), whereas the SEM demonstrated the extraction mechanism
with significant physical changes in matrix sample after treatment using
different solvents. Conclusion: Application of green chemistry principles
using an ionic liquid as a green solvent for the polyphenolic extraction of
P. pellucida herbs to be rapid, easy, and efficient. | |
