Allantoin is a compound contained in comfrey leaves. This research aims to obtain optimal condition parameters of ionic liquid-ultrasound-assisted extraction (IL-UAE) leaves attract allantoin compounds. Comfrey are extracted with eight liquids by ultrasound-assisted (UAE) and screened for levels. The best liquid from the screening results optimized response surface methodology (RSM) Box-Behnken...

This work aims to intensify trans-p-coumaric acid (p-CA) heterologous production. p-CA exhibits antimicrobial properties, low hydrosolubility, and retro-inhibition activity, making its production limited due accumulation in the broth. To overcome these limitations, an in-stream product recovery process (ISPR) is proposed consists a liquid-liquid extraction assisted by hollow fiber membrane cont...

In this study a new method of preconcentration, separation and efficient measuring of so-called hollow fiber solid / liquid phase microextraction has been introduced for the determination of trace amounts of lorazepam (LRZ) in water samples, urine and hair using differential pulse voltammetry. To this end, a hybrid adsorbent material was used that involved ionic liquid assisted magnetic multi-w...

Microwave assisted extraction (MAE) tech-nique was employed for the extraction of pectin from black mulberry (Morus nigra) pomace in this research. The effects of process variables namely microwave power (300-900 watt), irradiation time (10-30 min) and liquid to solid ratio (15-30 mL/g) on the yield, degree of esterification (DE) and galacturonic acid content (GalA) of pectin were investigated ...
