Ultrasound assisted liquid–liquid extraction in microchannels—A direct contact method

Sequential ultrasound-microwave assisted extraction as a green method to extract essential oil from Zataria multiflora

Sequential ultrasound-microwave associated extraction (SUMAE) is a combination of ultrasound waves and microwaves energies in which ultrasonic extraction is used as a pretreatment. It was performed to extract essential oil from Zataria multiflora. The extraction conditions were optimized by response surface methodology (RSM) and Central Composite Design (CCD). The antioxidant and antibacterial ...

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...

Optimization of phenol and flavonoid extraction compound of Adiantum capillus-veneris L. using ultrasound assisted extraction

Background: Antioxidants are molecules which able to control free radicals and prevent the oxidants of other molecules considering undesirable effects of synthetic anti oxidant. In recent years using of natural anti oxidant gets the great importance. The secondary metabolisms of plants are rich sources of phenol and flavonoids considered as the most important natural antioxidant.  Objective: In...

Effect of Ethanol Concentration in Ultrasound Assisted Extraction of Glycyrrhizic Acid from Licorice Root

Ultrasound-assisted extraction of capsaicinoids from peppers.

The development of a rapid, reproducible and simple method of extraction of the majority capsaicinoids (nordihydrocapsaicin, capsaicin, dihydrocapsaicin, homocapsaicin and homodihydrocapsaicin) present in hot peppers by the employment of ultrasound-assisted extraction is reported. The study has covered four possible solvents for the extraction (acetonitrile, methanol, ethanol and water), the op...
