Optimization of ultrasonic extraction of polysaccharides from Hovenia dulcis peduncles and their antioxidant potential

Extraction, characterization and antioxidant activity of water-soluble polysaccharides from Tuber huidongense

“…The ABTS radical scavenging activity was estimated by the method of Liu et al [21]. 4 mL of ABTS solution (7 M) was mixed with 0.2 mL polysaccharides of different concentrations.…”

“…The UAE process possess several advantages, including reduced solvent and energy consumption, while increasing the yield of extracts [17,18]. For these reasons, it has been widely utilized to obtain polysaccharides from different materials so far [19][20][21][22]. Interestingly no study has thus far investigated the extraction of truffle polysaccharides from THWP via UAE.…”

“…These results indicated that THWP-1 showed strong antioxidant activity and THWP-2 had moderate antioxidant activity. This might be explained by the factor that the monosaccharide composition Gal in THWP-1 would possess relatively higher antioxidant activity[21].3.5.3. ABTS radical scavenging assay activity ABTS assay is an accepted method in measuring the total antioxidant activity of a potential antioxidant.…”

Kinetics Study of Oil Extraction from Calophyllum inophyllum Seeds Using Ultrasonic-assisted Extraction Technique

“…The enhancement of oil yield during the diffusion stage could be due to the greater mechanical effects of ultrasound which is responsible for the efficient cell disruption of the seeds that leads to a more effective mass transfer of the oil into the solvent system. 26 However, beyond 210 W, the equilibrium oil yield for washing stage increased slightly and the equilibrium oil yield for diffusion stage did not show any significant changes. A higher ultrasonic power would cause an increase in the bubble numbers in the solvent during cavitation.…”

Characterization and bioactivities of polysaccharide from spentHovenia dulcispeduncles by alkali pretreatment

“…Based on medicine literature, most parts of H. dulcis, including peduncles, barks, seeds, and roots, are capable of slaking thirst, quenching acute alcohol toxicity, and anti-lipid peroxidation, among others. [3] Especially, polysaccharides are one of the main constituents of the H. dulcis peduncles, and play an important role in pharmacologic functions. Recently, some researchers studied the strong antioxidant activities, [3] immunostimulatory activity in vitro, [1] and hepatoprotective effect in vivo [4] of the polysaccharides from H. dulcis peduncles.…”
