title: Ultrasonic-assisted extraction of antioxidative compounds from Bene (Pistacia atlantica subsp. mutica) hull using various solvents of different physicochemical properties.
abstract: Extraction yield, phenolics content, and antioxidant activities of the materials extracted conventionally and/or ultrasonically from Bene hull by a number of aqueous and organic solvents were investigated. Higher extraction yields in general were obtained by the less polar solvents (12.1-47.5%). Polar protic solvents exhibited the highest content of total phenolics extracted (110-150 mg/g), followed by polar aprotic (30.0-43.5 mg/g) and non-polar solvents (3.3-5.2 mg/g). Good correlation (R(2)=0.9721) was obtained between the DPPH radical-scavenging activities and total phenolics contents. Many similarities were observed between the results of the DPPH (EC50=0.6-1105.3 μg/ml) and FRAP (0.1-8.5 mmol/g) assays. The highest oxidative stability index (OSI) value belonged to the methanol and water extracts, respectively. All the extraction factors significantly improved by 30 min sonication, especially in polar protic solvents. A 10-min sonication in water extraction could provide the same achievements as those of the 24-h conventional method.
