“…There are few studies on the examination of two species together and these studies revealed that linoleic and palmitic acid rates in N. sativa were higher than N. damascena while oleic acid rates in N. damascena were higher than N. sativa. The ratio of linoleic acid was found between 42.0 and 61.0 % in N. sativa in previous studies and the results were obtained within this range [23,24]. Our findings are also parallel to the previous studies in terms of linoleic acid 39-40 and oleic acid (28.1-36.0) rates in N. damascena [22,25].…”

Nigella sativa and N. damascena are major spices and aromatic plants that are cultivated commonly in Turkey. The fatty acid compositions of full maturated seeds in the species were compared in the research. Variations in the fatty acid composition of the oil in the species were also examined during the four maturation stages of seeds, immature, premature, mature, and delayed mature. Quantitative variation in the fatty acid compositions were significantly (p \ 0.01) different between the species. Linoleic and palmitic acid contents were higher statistically (p \ 0.01) in N. sativa with 57.0 and 12.5 %, respectively while the oleic acid content was higher in N. damascena with 32.2 %. During the maturation stages, linoleic acidthe main fatty acid in both species-contents decreased regularly from 57 to 51 % during maturation stages in both species. On the other hand, the oleic acid amount (the main saturated fatty acid in both species), increased from immature stages to delayed mature stages and were found to be 20.0 and 27.2 %, respectively. According to the results, it can be concluded that harvesting from fully mature stages is preferable than other stages. This is due not only to the significant difference in fatty acid content of immature and premature stages but also the harvesting loss of the delayed maturation stages.

“…The number 41 is the molecular weight of glycerol without OH groups. The molecular weight values of oils (sunflower 875.02, olive 884.71, virgin coconut oil 678.39, and ginger 873.9 g/mol) which were found by equation (7), have a good agreement with those reported in the literature [23].…”

“…Based on differences in physicochemical properties, there are several technologies available to determine and purify individual MUFAs and PUFAs. Gas chromatography-mass spectrometry (GC-MS) is the main technique to determine fatty acids in a variety of samples [4], such as salmon oil [5], milk products [6], nigella sativa oil [7], and sesame oil [8]. Common methods to obtain fractions rich in unsaturated fatty acids include molecular distillation, liquid chromatography, and argentated silica ISSN: 0067-2904 Saber et al…”

The core objective of this study was to investigate the physicochemical characteristics and fatty acid composition of the oils of sunflower, olive, virgin coconut and ginger oils, as well as the separation of their unsaturated fatty acids. The data indicated a significant variation in physicochemical properties (acid, saponification, ester, and iodine values) among oils. Transesterification process was carried out at a molar ratio of 1:7:0.1 of oil: methanol: KOH. Fatty acid methyl esters of oils were analyzed by infrared (IR) and gas chromatography–mass (GC-MS) spectrometry. Twelve fatty acids were identified, where the major fatty acid of olive oil was found to be oleic acid (89%), whereas those of sunflower and ginger oils were linoleic acid (80.9 %) and (79.3 %), respectively. Sunflower and olive oils were fractionated by 25% silver nitrate-impregnated silica gel column chromatography. By this method, linoleic acid methyl ester from sunflower and oleic acid methyl ester from olive oil were isolated with high purity percentages and yields. This study is significant for the development of food and pharmaceutical products.

“…The complexes formed with unsaturated fatty acids such as linoleic acid and oleic acid, were reported to cause cytotoxicity against different cancer types, induce apoptosis as well as restrict tumor growth and progression in vivo [70][71][72][73]. In addition, highunsaturated fatty acid contents in NS pulp can be useful contribute considerable resistance to oxidative reactions on food storage in particular [74]. There are many studies in the literature on NS extract.…”

Ö ZB u çalışmanın amacı, yağ çıkarma işlemi sonrasında atık materyal olarak ortaya çıkan çörek otu (Nigella sativa L.-NS) posasının anti-oksidan, anti-metastatik ve anti-anjiyojenik özelliklerinden yola çıkarak biyolojik etkinliklerini incelemektir. NS posasından çıkarılan özütün UV-görünür bölge (UV-vis), Fourier Dönüşümlü Kızılötesi (FTIR) ve gaz kromatografisi-kütle spektrometresi (GC-MS) ölçümleriyle karakteristiksel özellikleri incelendikten sonra 2,2-difenil-1-pikrilhidrazil (DPPH) ve Trolox eşdeğer antioksidan kapasitesi (TEAC) yöntemleri kullanılarak anti-oksidatif kapasitesi tayin edilmiştir. Posa özütünün anti-proliferatif etkileri, etkilerin hücre tipine özgü olup olmadığını incelemek amacıyla hem kanser hem de kanser olmayan hücreler üzerinde test edilmiştir. Anti-anjiyojenik testler civciv korioallantoik membran testi (CAM) aracılığıyla gerçekleştirilmiştir. Sonuçlar NS posa ekstratının radikal süpürücü etkilerini halen muhafaza ettiğini ve normal hücreler ile karşılaştırıldığında kanser hücre proliferasyonunu daha etkin bir biçimde düşürdüğünü göstermiştir. Ayrıca CAM testleri NS posa özütünün VEGF uyarımlı vaskülarizasyon ve gelişimini etkin bir biçimde sınırladığını göstermiştir. NS posa özütü metastatik hücre topluluklarının baskılanmasında ve kanser başta olmak üzere patolojik anjiyogenez ile seyreden hastalıkların tedavisinde faydalı sonuçlar üretebilir. Bu çalışma bitkisel kaynaklı atık maddelerin birçok alanda çok çeşitli amaçlar doğrultusunda kullanılmak üzere geri dönüştürülebileceğine dikkat çekmektedir. Anahtar KelimelerÇörek otu, kanser tedavisi, anti-anjiyojenik aktivite, korioallantoik membran testi. A B S T R A C TT he aim of this study is to investigate the biological activities such as antioxidative, antimetastatic and antiangiogenic properties of the Nigella sativa L. (NS) pulp, which is a waste material of the oil production process. Following the investigation of the characteristic properties of NS pulp extract with UV-visible (UVvis), fourier-transform infrared (FTIR) and gas chromatography-mass spectroscopy (GC-MS) measurements, its antioxidative capacity was determined using 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and Trolox equivalent antioxidant capacity (TEAC) assays. Antiproliferative effects of the pulp extract were tested on both cancerous and non-cancerous cells to examine whether the effects are specific to cell types. Antiangiogenic tests were performed via chick chorioallantoic membrane (CAM) assay. The results showed that the NS pulp extract still maintained its radical scavenging effects and reduced the proliferation of cancer cells more efficiently compared to non-cancerous cells. Furthermore, CAM assays demonstrated that the pulp extract effectively limited vascular endothelial growth factor (VEGF)-stimulated vascularization and development. NS pulp might be used for the suppression of the metastatic cell populations and for the treatment of the diseases particularly like cancer, which progress with pathological angiogenesis. This study highlights that such waste ma...
