“…The selection of 70% (v/v) ethanol in water was in concordance with results obtained by other authors from the determination of natural phenols in different samples, because extraction efficiency depends on the solubility of the analytes in the extraction solvent. 12,14,22,25 Hughey et al 5 studied the distribution of polyphenols from almond skin in blanch water as a function of time and temperature, the intrinsic solubility of each polyphenol in water being different depending on its structure. In general, major phenolic compounds present in almond skin are sparingly soluble in hot water.…”

26A microwave-assisted extraction (MAE) procedure to isolate phenolic compounds from 27 almond skin by-products was optimized. A three-level, three-factor Box-Behnken 28 design was used to evaluate the effect of almond skin weight, microwave power and 29 irradiation time on total phenolic content (TPC) and antioxidant activity (DPPH). 30Almond skin weight was the most important parameter on the studied responses. The 31 best extraction was achieved using 4 g, 60 s, 100 W and 60 mL of 70% (v/v) ethanol. 32 TPC, antioxidant activity (DPPH, FRAP) and chemical composition (HPLC-DAD-ESI-33MS/MS) were determined by using the optimized method from 7 different almond 34 cultivars. Successful discrimination was obtained for all cultivars by using multivariate 35 linear discriminant analysis (LDA) suggesting the influence of cultivar type on 36 polyphenols content and antioxidant activity. The results showed the potential of 37 almond skin as a natural source of phenolics and the effectiveness of MAE for the 38 reutilization of these by-products. 39

“…In recent years, MAE has been widely applied for extracting bioactive subtracts from plants and has become popular for phenolic compounds extraction, such as Sour Cherry Pomace (Simsek et al, 2012), Rosmarinus offi cinalis (Švarc--Gajic et al, 2013), Canarium album L. (He and Xia, 2011), etc. In comparison with conventional methods, MAE reduces the amount of solvents, cuts the extraction time considerably and increases the yield (Huie, 2002).…”

A procedure focused on microwave-assisted extraction in open vessel (MAE-OV) and gas chromatography with electron capture detection (GC-ECD) was used for the determination of 26 congeners of polychlorinated biphenyls (PCBs) in soil samples. The limit of detection (LOD) and limit of quantification (LOQ) were evaluated for commercial PCBs mixture Aroclor1260. LOD and LOQ were calculated for each PCB congener, in the ranges (0.03-0.27 ng g −1 ) and (0.11-0.70 ng g −1 ), respectively. After optimization, 26 PCBs congeners were successfully extracted from soil samples with recovery amounts ranging between 84.7% and 117.3% for all PCBs congeners. The evaluated method of MAE-OV showed good separation and extraction of all PCBs congeners from soil samples. Extraction parameters such as solvent choice, power and extraction time were investigated. This study indicated that MAE-OV could be an interesting alternative method to extract PCBs from soils, since it is economical, easy, fast and requires low amounts of solvents.ARTICLE HISTORY
