“…High values of FFA observed in acorn oils may be caused by the bad conservation of the fruits before extraction and analysis or the incomplete ripeness of the seeds [12]. e specific gravity of the oil extracted from acorn ranges from 0.912 to 0.922 [2,30], similar to the specific gravity of diesel oil (1.0) [29].…”

“…It has been reported that acorn oils presented a remarkable antioxidant activity, up to 3.34 and 3.79 µmol TE g −1 oil (DPPH and ABTS test, respectively) [21]. In addition, [30] suggested that the strong antioxidant ability of acorn oil (IC50 : 170.5 µg/ml and 265.5 µg/ml, by DPPH and β-carotene bleaching assay, respectively) is possibly due to the presence of the phenolic compounds, α-tocopherol, flavonoids, and numerous different fatty acids.…”

Acorn oil has been receiving increasing attention due to its nutritional potentials. However, its application as a novel food ingredient has not yet been fully explored. This paper summarizes chemical composition, extraction methods, potential health benefits, and current applications of acorn oil, with the aim of providing suggestions for its exploitation. Acorn oil is an excellent source of essential fatty acids (oleic, linoleic, α-linolenic, and palmitic acids). Acorns are a rich source of tocopherols, with γ-tocopherol being the most abundant. It also contains various bioactive compounds such as polyphenols and sterols (mainly β-sitosterol). Diets enriched with acorn oil can be beneficial in preventing cardiovascular disease (CVD), cancer, and type 2 diabetes as well as offer antioxidant activity. Further studies should focus on producing better quality acorn oil such as the application of more innovative and optimized techniques that can increase its health benefits and hence utilization.

“…Asam palmitat termasuk asam lemak jenuh yang memiliki aktivitas sebagai antimikroba, antivirus, antiprotozoa, antifungal dan antibakteri (Rahmaningsih dan Andriani, 2017). Berdasarkan hasil penelitian El-Agbar, et al, (2018) gal manjakani yang berasal dari daerah Jordan mengandung asam palmitat = 15,99%. Sementara itu, gal manjakani yang berasal dari daerah Turki mengandung asam palmitat = 18,29% (Kaplan, et al, 2019).…”

Gal manjakani (Quercus Infectoria) is one of the most popular medicinal plants in Asia. This plant is found in Turkey, Syria, Persia, Cyprus, and Greece. This study aims to determine the compounds contained in the non-polar fraction and to determine the antibacterial activity and toxicity of the fraction. Gal Manjakani was extracted by maceration method with acetone then fractionated with n-hexane, ethyl acetate and methanol. Non-polar fractions were analyzed using Gas Chromatography-Mass Spectroscopy (GCMS). The antibacterial activity test used disc diffusion and microdilution methods based on the CLSI standard method against Staphylococcus aureus and Escherichia coli bacteria. Toxicity test was conducted using the Brine Shrimp Lethality Test (BSLT) method. The GC-MS identification results showed that the non-polar fraction of gal manjakani contained 27 compounds, with the main compounds being cis-vaccenic acid (35.19%), n-hexadecanoic acid (16.66%), 1-heptadecan carboxylic acid (5.03%), dodecanoic acid. (4.73%), bis (2-ethylhexyl) phthalate (4.35%), hexadecanoic acid, methyl ester (2.14%) and tetradecanoic acid (1.31%). The results of the antibacterial activity test showed activity with an inhibition zone of 6.26 ± 0.6 mm against S.aureus bacteria and 8.23 ± 0.21 mm against E.coli bacteria, with a percentage of effectiveness against S.aureus bacteria of 15.34% and for E. coli 44.24%. The MIC and MBC values of S.aureus bacteria were> 5000 (µg / mL) and> 5000 (µg / mL) and E. coli was 312.5 (µg / mL) and> 5000 (µg / mL). The results of the toxicity test showed that the non-polar fraction of gal Manjakani was toxic with an LC50 value of 2.1527 ppm.

Aerial parts of Mercurialis annua L. were used in the present study, and fatty acid content in lipid extract was determined using GC-FID. The major fatty acids identified were αñlinolenic acid (20.3%), heptadecanoic acid (12.8%), palmitic acid (11.9%), pentadecanoic acid (11.7%), cis-10-pentadecanoic acid (11.2%), linoleic acid (7.7%), tridecanoic Acid (4.6%), stearic (4.4%), cis-11,14-eicosadienoic acid (3.8%), beside of minor fatty acids (palmitoleic acid, cis-13,16-docosadienoic acid, arachidic acid, behenic acid, cis-10heptadecenoic acid and myristic acid). Antioxidant properties of the extract were determined via DPPH radical scavenging, β-carotene bleaching assay and NO radical scavenging assay. The extract produced significant antioxidant activity in-vitro. The data shown here may broaden our knowledge on composition and antioxidant activity of lipid constituents from Mercurialis annua L.
