The purpose of this study is to assess and evaluate the physicochemical properties of the seed oils of two Moroccan varieties of watermelon “Citrullus lanatus” extracted by three different techniques, a mechanical process using cold press, and two chemical processes using a Soxhlet apparatus and a sonotrode ultrasound assisted extraction (UAE) using n-hexane. The total phenolic compounds (TPC) and antioxidant properties against the DPPH radicals (2,2-diphenyl-1-picrylhydrazyl) were also studied. The seed oils of both varieties of watermelon exhibited high concentrations of unsaturated fatty acids with the predominance of linoleic and oleic fatty acids. The primary sterol was β-sitosterol, and high levels of total tocopherols were observed. Ɣ-tocopherol was the predominant tocopherol in all tested oils. The Citrullus lanatus var. lanatus variety seeds oil exhibited the highest TPC value (89.5 ± 0.06 mg EGA/100 g; EGA: gallic acid equivalent), with 82.4 ± 0.03% DPPH free radical inhibition efficiency. Nevertheless, all tested seeds oils showed a significant amount of total phenolic compounds and a good inhibition against DPPH radicals ranging from 51.1 ± 0.1% to 84.8 ± 0.04%. In addition, the influence of the ultrasonic extraction parameters was studied using two different solvents (n-hexane and the methanol-chloroform mixture), with different particle sizes (500–300 µm), duration (10 and 20 minutes), cycle (1–0.5), amplitude (80–100%) and solvent/seed ratios (1:5 and 1:10), and the seed roasting parameter was also studied. The oil yield was mainly affected by the extraction solvent, then the solvent/seed ratio and the duration, respectively.

Seed oils have been used for centuries by communities as food, medicine, cosmetic applications, and fuel. Recently, there has been a renewed interest in these nontimber forest products specifically for use in cosmetic formulations. The fatty acid compositions of kernel oil of Heynea trijuga was analyzed by GC-FID. The results showed that the oil content was 37.61 percent (w/w) in seed. Seed oil was rich in unsaturated fatty acids. Important fatty acids present were palmitic acid (22.12%), stearic acid (7.51%), oleic acid (25.20%), and linoleic acid (11.65%).

Abstract The chemical properties, mineral contents, fatty acid and tocopherol contents of seed and seed oils of some citrus genus provided from several locations in Turkey and Saudi Arabia were determined. While Ca contents of seeds were between 5018 mg/kg (Kütdiken lemon) and 7619 mg/kg (kinnow mandarin), K contents of seeds varied between 7007 mg/kg (Orlando orange) and 10334 mg/kg (kinnow mandarin). Glucose and fructose contents of citrus seed samples varied between 3.75 g/kg and 5.75 g/kg, and 4.09 g/kg and 6.03 g/kg. Palmitic, oleic and linoleic acids were established as dominant fatty acids. Palmitic, oleic and linoleic acid contents of citrus seed oils varied between 19.6% (Kütdiken lemon) and 26.2% (pineapple orange), 21.3% (kinnow mandarin) and 31.4% (Kütdiken lemon) and 32.3% (Kütdiken lemon) and 43.7% (kinnow mandarin), respectively. The total amount of tocopherols of Turkish citrus oil varied between 0.5 mg/100 g (Fremont mandarin) and 18.8 mg/100 g (bitter orange).
