The lipid fraction ofPistacia atlanticaseeds was extracted for the first time by means of cold-press technique and analyzed for its chemical composition. The fatty acids, sterols, triacylglycerols (TAG), tocopherols, polyphenols, and pigments were identified and their concentrations were determined by means of reversed-phase high-performance liquid chromatography (RP-HPLC) and gas chromatography (GC). Because of its high content of unsaturated fatty acids, it might prove to be of value in diets and it may be used as edible cooking or salad oils or for margarine manufacture.Pistacia atlanticaseed oil has the unique sterols and tocopherols content providing source of natural antioxidants. The main triacylglycerols were SLL + PLO, SOL + POO, OOLn + PLL, OOO, and SOO. This paper examined the phenolic fraction ofPistacia atlanticaseed oil. Moreover, caffeic acid followed by cinnamic acid, pinoresinol, vanillin,p-Coumaric acid, ferulic acid, ando-Coumaric acid was also determined. This paper presents the first investigation of chlorophyll's and carotene's composition inPistacia atlanticaseed oil. Furthermore, pheophytin a was the major component, followed by luteoxanthin, neoxanthin, violaxanthin, lutein, lutein isomers, chlorophyll a, chlorophyll a′, and pheophytin a′ were also determined.

A novel surfactant-assisted dispersive liquid-liquid microextraction (SADLLME) based on solidification of floating organic drop (SFO) combined with high-performance liquid chromatographyultraviolet detection (HPLC-UV) has been proposed for extraction and determination of amphetamine (AM) and methamphetamine (MA) in urine samples. 1-undecanol and sodium dodecyl sulfate (SDS) were used as extracting solvent and disperser, respectively. Face-centered central composite design (FCCCD) was used for optimization of several factors affecting extraction recovery. The optimal conditions were pH ¼ 6.4, volume of extracting solvent V ¼ 31.0 mL, 0.08 CMC as surfactant concentration, and the amount of NaCl for ionic strength was 0.3% (W/V). The limits of detection (LODs, S/N ¼ 3) of the extraction method were 2 for AM and 3 mg L À1 for MA, with the enrichment factors (EFs) of 56 and 48 folds, respectively. The relative standard deviation (RSD %) for n ¼ 3 was below 5.6% and a good linearity (R 2 > 0.991) in the range of 10-2000 mg L À1 was observed. The application feasibility of SFO-SADLLME-HPLC-UV in real sample was investigated by analyzing different real samples and satisfactory results were obtained.
