“…Seeds were ground into powder using a mill. The milled samples were homogenized in 10 mL of hexane-isopropanol (3:2), centrifuged at 5000 rpm for 10 min (Kaplan et al 2019); after 2.5 mL of 2% methanolic sulfuric acid was added, the mixture was vortexed. This mixture was incubated for 15 h at 50 °C, cooled to room temperature, and vortexed after adding 2.5 mL of 5% NaCl.…”

The fatty acids content in pine seeds is important because it affects germination success and commercial value. In this study, the amount of fatty acids in the seeds of stone pine (Pinus pinea L.) was determined in seeds collected from different geographical locations and after two-year storage. The pine seeds were collected from different locations where peanut pine is densely located in the Western Black Sea Region of northern Turkey in 2019. The results showed that the content of some fatty acids (C18:1n-9, ƩMUFA, C18:2n-6, and ƩPUFA) in the seeds collected from different geographical locations did not differ significantly, but the content of others (C16:0, C18:0, C20:0, ƩSFA, and C18:3n-3) was dependent on the locations. The difference among locations was up to 40% (p < 0.05). In general, the lowest values were obtained from the seeds of Bartın Karaçaydere, and the highest values were obtained from the seeds of Bartın Çakraz and Bartın Avara locations. After two years of storage, the content of all the fatty acids in the seeds decreased based on the location, and a decrease of more than 25% in the content of some fatty acids was observed.

“…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). Bila dibandingkan dengan kedua daerah tersebut kandungan asam palmitat gal manjakani yang tumbuh didaerah Sumatera Utara lebih besar dari daerah Jordan dan lebih kecil dari daerah Turki.…”

“…Sementara itu, gal manjakani yang berasal dari daerah India mengandung asam stearate = 26,52% (Nair, et al, 2020). Hasil penelitian Kaplan, et al, (2019) dengan menggunakan gal manjakani yang berasal dari Turki mengandung asam stearat = 3,08%. Dari data tersebut kadungan asam stearat gal manjakani yang berasal dari daerah Sumatera Utara lebih besar dari daerah Jordan dan Turki.…”

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.
