The interest in natural phenolic compounds has increased because of their attractive use especially as antioxidant and antimicrobial agents foods. large content Santolina chamaecyparissus L. (S. chamaecyparissus) makes this plant a target source that is worthy note. In work, new extraction technologies comprising ultrasound (UAE) microwave (MAE) assisted the S. have been developed, optimized, c...

Drying is one of the widely used methods of food preservation and it is a sensitive food processing operation due to undesirable changes in the quality of dried product. In this study the effect of osmotic dyhedration and ultrasound pretreatment prior to convective drying on quality properties of apple slices was investigated. Apple slices were pretreated by osmotic dehydration in two concentra...

Teh ultrasound-assisted magnetic stirrer was used as an effective extraction technique for teh evaluation of total phenolic contents (TPC) and antioxidant potential of ten Pakistani brown rice cultivars. For this purpose, ultrasonic (240W frequency 50/60 Hertz) assisted magnetic stirrer coupled with three solvents methanol, ethanol, and isopropanol in pure and aqueous fractions (80:20) were...

BACKGROUND Tithonia diversifolia belongs to the Asteraceae family. The leaves of T. diversifolia have been studied lately because of the presence of tagitinin C. OBJECTIVE Looking for an easy and inexpensive method to extract tagitinin C from T. diversifolia leaves, this work aims to conduct a screening to evaluate the influence of different experimental factors using the dynamic maceration a...

The bioactive components of malacca (Emblica officinalis), which consist phenolic, alkaloids, phytosterols, organic acids, and vitamins, are valuable for human health. T he yield quality the in extract highly depend on extraction technique, so it is essential to know development research techniques fruit. In addition, have limitations their application due stability, solubility, absorption, bio...

In a supercritical fluid extraction (SFE) unit, one generally can change the temperature, pressure, extraction bed size, solvent flow rate, among others, in order to maximize the global yield. The morphology of the solid substrate particle can also influence the extraction efficiency, since the solvent must cross diffusive paths inside the solid particle, in order to extract specific compounds ...

Kinetic modeling and optimization of musk willow (Salix aegyptiaca L.) essential oil extraction process using ultrasound assisted hydrodistillation

Organic impurity profiling of seized 3,4-methylenedioxymethamphetamine (MDMA) tablets aims to link tablets to common production sources. Conventionally, organic impurities are extracted from tablets using a liquid-liquid extraction (LLE) procedure prior to analysis by gas chromatography-mass spectrometry (GC-MS). In this research, the development of an alternative microwave-assisted extraction/...

An ultrasound and microwave assisted alternant extraction method (UMAE) was applied for extracting dihydroquercetin (DHQ) from Larix gmelinii wood. This investigation was conducted using 60% ethanol as solvent, 1:12 solid to liquid ratio, and 3 h soaking time. The optimum treatment time was ultrasound 40 min, microwave 20 min, respectively, and the extraction was performed once. Under the optim...
