Optimization of pulsed ultrasound-assisted technique for extraction of phenolics from pomegranate peel of Malas variety: Punicalagin and hydroxybenzoic acids.

Pomegranate peel is a rich source of phenolic compounds (such as punicalagin and hydroxybenzoic acids). However, the content of such bioactive compounds in the peel extract can be affected by extraction type and condition. It was hypothesized that the optimization of a pulsed ultrasound-assisted extraction (PUAE) technique could result in the pomegranate peel extract with higher yield and antio...

A Box-Behnken experimental design for microwave assisted extraction optimization of pectin from citron peel

Microwave assisted extraction technique was employed to extract pectin from citron peel. Box-Behnken design was applied to investigate the influence of irradiation time, microwave power and pH on the yield and DE of pectin. The finding indicated that the optimal conditions for the maximum yield of pectin (30.71%) were achieved at irradiation time of 3 min, microwave power of 700 W and pH of 1.5...

Optimization and Comparison of Ultrasound-Assisted Extraction of Estragole from Tarragon Leaves with Hydro-Distillation Method

A comparative study of ultrasound-assisted extraction (UAE) and hydro-distillation was performed for fast extraction of estragole from tarragon (Artemisia dracunculus L.) dried leaves. Several influential parameters of the UAE procedure in the extraction of estragole (type of solvent, extraction cycles, solvent to material ratio, irradiation time and particle size) were investigated an...
