Ultrasonic-assisted extraction and in-vitro antioxidant activity of polysaccharide from Hibiscus leaf

Prebiotic oligosaccharides from artichoke industrial waste: evaluation of different extraction methods

“…Emerging technologies have been used in order to develop new and environmentally friendly methods, reducing processing time, enhancing heat and mass transfer and improving product quality and functionality (Galanakis, 2013). Among these techniques, ultrasound (Prakash Maran et al, 2013;Afshari et al, 2015) and microwave-assisted extraction (Xie et al, 2010;Zheng et al, 2015), high pressure microfluidization-assisted extraction (Huang et al, 2012;Zhang et al, 2015), pulsed electric field (Zhu et al, 2012;Parniakov et al, 2014) have reported to recover oligo-and polysaccharides from plant tissues.…”

Optimization of ionic liquid based ultrasonic assisted extraction of antioxidant compounds from Curcuma longa L. using response surface methodology

“…Among these methods, UAE has been widely used to extract phytochemicals from many matrixes as an efficient, energy-saving, environmental friendly extraction technique. It offers short extraction time, high extraction efficiency, low solvent consumption and energy input and is suitable for the extraction of heat sensitive material (Afshari et al, 2014;Asfaw et al, 2005;Fang et al, 2014;Zhang et al, 2011).…”

Monosaccharide composition analysis of immunomodulatory polysaccharides by on‐line hollow fiber microextraction with high‐performance liquid chromatography

“…Performing 2.0 h extraction without ultrasonic waves gave similar results to 1.5 min extraction under ultrasonic waves. According to the few researches of LPME performed with ultrasonication , membrane‐based LPME could be accelerated by ultrasonic waves because of more effective mixing of the extracted phase with the sample. It was also found that the peak areas decreased with the increasing extraction time.…”
