“…Total phenolic content, using Folin-Ciocalteu reagent, was carried out according to the procedure reported in the literature [31]. The total phenol content was calculated from a standard curve of gallic acid and results were expressed as mg of gallic acid equivalents (GAE) per 100 mL of sample.…”

Abstract-In this present study, the antioxidant properties of kefir produced from goat milk with kefir grains were investigated. The antioxidant capacity of kefir was evaluated by assessing the DPPH (2,2-Diphenyl-1-picrylhydrazyl), the ABTS-based method [2,2'-azino-bis-(3-ethylbenzthiazoline-6-sulphonic acid)] radical-scavenging activity and ferric reducing antioxidant power (FRAP) at different stages of fermentation and storage period. Generally, the antioxidant capacity of goat milk-kefir samples was mainly dependent on the fermentation and storage period and good stability in DPPH, ABTS and FRAPS assays. During fermentation and storage, the total phenolic content in samples demonstrated significantly decreased.

“…There are number of other techniques like accelerated solvent extraction, microwave-assisted extraction and supercritical fluid extraction, used for extraction of polyphenols from different biomaterials but the best alternative is ultrasound assisted extraction (UAE) due to simplicity, inexpensiveness and higher efficiency (Sahin et al 2013). During the ultrasound extraction, the collapsing of acoustic cavitation bubbles releases high energy that accelerates the microstructure breakdown of conjugating bond in phenolic esters, glycosides and bound complexes (Wanga and Zuo 2011).…”

In this study, extraction of polyphenols using different solvents (acetone, ethanol, methanol and water) with ultrasound and conventional method from whole mung bean (WMB), hull and cotyledon was conducted. Total phenolic content (TPC), total flavonoids content (TFC), total antioxidant activities (TAA), ferric reducing power (FRP) and DPPH radical scavenging activity were determined. Ultrasound treated extracts exhibited higher TPC, TFC, TAA, FRP and DPPH in different mung bean fractions than CSE. Among the solvents, acetone showed better TPC, TFC, TAA, FRP and DPPH. Hull had significantly higher TPC, TFC, TAA, FRP and DPPH than WMB and cotyledon. Sinapic acid (SA) was the major polyphenol in different fractions. Acetone extract of hull showed high polyphenol content. SA, ferulic acid, catechin, p-coumaric acid, resveratrol, quercetin and luteolin were the major contributors to antioxidant activity of acetone extract. Mung bean hull contained the maximum polyphenols and acetone was observed to be the best extraction medium for polyphenols in combination with ultrasound.

“…The positive influence of polar organic solvent, such as ethanol and methanol, on TP and TF, as well as favorable influence of low pH [10] has previously been observed in extraction of several plant species including Artemisia absinthium, Allium ursinum and Myrcaria species. [28] The amount of TPA in the prepared extracts was between 0.120 mg/ml and 0.271 mg/ml. Their content depended mostly on temperature of the extraction solvent, both as linear and quadratic term, as well as on its interaction with pH.…”

Response surface methodology was used to optimize experimental conditions for ultrasound-assisted extraction of functional components from Medicago sativa L. (Fabaceae) aerial parts. The procedure was performed according to the Box-Behnken design. The independent variables were ethanol concentration (X1), temperature (X2), and pH (X3), while the responses were extraction yield, DPPH radical scavenging activity of the extracts (RSA IC50), content of total phenols (TP), total flavonoids (TF) and total phenolic acids (TPA). The response values of the extracts prepared at optimum conditions (X1, X2, X3) were: yield (162 mg/ml, 20 %, 60 °C, 5.5), TP (6.63 mg/ml, 100 %, 60 °C, 5.5), TF (0.292 mg/ml, 100 %, 23 °C, 5.5), TPA (0.275 mg/ml, 100 %, 23 °C, 8.5) and RSA IC50 (3.97 mg/ml, 40 %, 60 °C, 7.0). The predicted values matched well with the observed ones indicating the suitability of the selected models for extraction of bioactive compounds from M. sativa.
