“…From data in Table (2) acid value in vegetable oils: namely Virgin olive, corn, sunflower and sesame oils reported 0.989, 0.136, 0.198 and 0.921 mg/g, respectively, these results agreed with (Squires, 1991 andAl-Sherbini et al, 2018) who reported the acid value of corn oil ranged from 0.1-1.1 mg/g (Rey, et al, 2001;Cao, et al, 2015 andGrossi, et al, 2014) who reported the acid value ranged from 0.8-2%. It was decided that the acidity of olive oil should be according to decide by the International Olive Council (IOC) in 2015 that the acidity be as follows: extra-virgin olive oil (0.8%), virgin olive oil (2%), and ordinary olive oil (3.3%).…”

This study was designed to determine fatty acids composition in some Egyptian vegetable oils namely virgin olive, sunflower, corn, and sesame seed oils. Obtained results using gas chromatography (GC) showed that these oils are a good source of monounsaturated fatty acids (MUFAs) because the highest of Monounsaturated Fatty Acids (MUFAs) that reported being 63.62% in virgin olive oil, sunflower oil 28.04, corn oil 28.21 and sesame oil 43.3%, respectively. Also, n-3 PUFA represented by α-linolenic acid (ALA, C18:3, n-3) were virgin olive oil, sunflower oil, corn oil and sesame oil at the ratio of 0, 27%, 0.53%, 0.54% and 0.4%, while n-6 PUFA virgin olive, sunflower, corn, and sesame oils were represented by linoleic (LA, C18:2, n-6) at the ratio of 24.65%, 57.36%, 57.00% and 41.33%. Virgin olive oil and Sunflower oil had high amount of free radical scavenging capacity (IC50‫23.615؛‬ mg and 2278.643, respectively). While Sesame oil and corn oil had relatively low capacity (IC50‫24.9542؛‬ mg and 132179.8 mg, respectively) in compared with ascorbic acid (IC50:10 µ/ml). The highest amount of phenolic compounds was 1.3095g GAE/100g in virgin olive oil, while the lowest oil one in phenolic compounds was sunflower oil reported by 0.1641g GAE/100g. Antibacterial activity has not been detected in the all analyzed vegetable oils.

“…About 10 ml of 5 × 10-3 mol / dm3 of HAuCl4 added drop by drop to 100 ml of oleic acid at 200 °C. Heating was continued for an additional 5 minutes after which, the solution removed from the heater and stirred for 15 minutes until, the color turned into orange-brown ("as discussed elsewhere [15][16][17]"and modified by Al-Sherbini et al [18].…”

HE aim of the study is to explore the antidiabetic and antioxidant activities of gold nanoparticles (AuNPs) mixed with either flaxseed oil (FLO) or fish oil (FIO). A pyrolysis method was used to prepare AuNPs in oleic acid. The characteristics of the sample were determined by using the transmission electron microscope (TEM) and UV spectroscopy. Male albino rats were divided into two main groups. Group one (n=10 rats) was fed on the basic diet (serves as healthy control). The other group was fed on the high fructose diet (HFD) for four weeks and then was divided into five subgroups. 1 st subgroup was fed on HFD only, 2 nd and 4 th subgroups were fed on HFD mixed with omega-3 oils while 3 rd and 5 th fed on HFD+ omega-3 oils mixed with AuNPs. Results revealed that there was a significant decrease in glucose level, serum insulin, homeostasis model assessment of insulin resistance (HOMA-IR) index and lipid peroxidation in oils nanoparticles treated groups compared to the HFD group and a significant increase in the homeostasis model assessment of β-cell function (HOMA-β) and Glutathione (GSH). It can be concluded that AuNPs mixed omega-3 oils have more anti-diabetic, hepatic protection and antioxidant properties than omega-3 oils alone.

This study aimed to evaluate the hypolipidemic, and anti-obesity effects of polyunsaturated oils, mixed with gold nanoparticles (AuNPs). AuNPs were prepared by the oleic acid pyrolysis method. The sample was characterized by UV spectroscopy and transmission electron microscope (TEM). Sixty adult male rats were divided into 2 main groups. Group one (n=10 rats) was fed on the healthy diet (serves as basic control). The other group was fed on the high fructose diet (HFD) for four weeks and then was divided into five subgroups. 1st subgroup was fed on HFD only, 2nd and 4th subgroups were treated with n-3 PUFAs oils while 3rd and 5th treated with n-3 PUFAs oils mixed with AuNPs. Treatment of obese rats with n-3 PUFAs mixing with AuNPs revealed a significant decrease in in weight gain accompanied by an improvement of lipid profile. Histological examination of the heart indicated a marked improvement in the architecture and marked decrease of relative weight of heart in treated rats. It may be concluded that mixing of PUFAs oils with AuNPs could have the ability to lower weight gain of obese rats and relieved the various biochemical and histological abnormalities resulted due to obesity metabolic disorders.
