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 and optimiz...

various novel techniques including ultrasound-assisted extraction, microwave-assisted extraction and supercritical fluid extraction have been developed for the extraction of medicinal plants in order to shorten the extraction time, decrease the solvent consumption, increase the extraction yield, and enhance the quality of extracts. this review was conducted to introduce and compare the conventi...

The present research describes the use of directly suspended drop microextraction and air-assisted dispersive liquid-liquid microextraction method coupled with UV-Vis spectrophotometer for the analysis of doxepin in water and biological samples. Several important parameters which influence the extraction efficiencies of these two microextraction methods, such as the kind of extracting solven...

Abstract A rapid, sensitive, economically and ecologically friendly method based on one-step ultrasound-assisted emulsification microextraction in situ derivatization followed by gas chromatography–mass spectrometry for simultaneous determination of low molecular benzotriazoles benzotriazole-based ultraviolet filters was developed. The optimized allows quantification benzotriazole, 4-methylbenz...
