“…The highest concentration of total phenolic compounds and flavonoids were found in the NS capsules and oil followed by the methanol and aqueous extracts, with a linear relationship between free radical inhibition and total polyphenols 45 . NSS oil has a high ratio of unsaturated per saturated fatty acids and the oil extracted with dichloromethane has the highest amounts of thymoquinone 46 . High level of antioxidants could be derived from NSS oil extracted by supercritical fluid extraction than cold press 47 .…”

“…Thymoquinone diminishes the apoptotic changes in Leydig cells as reported in previous investigation 22 . NSS is a rich source of unsaturated fatty acids 46 which stimulate the activity of 17 β-hydroxysteroid dehydrogenase 56 , a key regulatory enzyme in the pathway of testosterone biosynthesis, by changing phospholipid composition in the plasma membranes of testes which alters the receptor-mediated gonadotropin actions 57 . Conjugated linolenic acid in NSS, as octadecadienoic in Leydig tumour rat cells and trained mice, up-regulated specific genes encoding enzymes and transport proteins involved in testosterone biosynthesis 58 .…”

Monosodium glutamate (MSG) is one of the most widely spread food additives that might cause male infertility. However, Nigellasativa L. seeds (NSS) could provide a solution. This study was designed to investigate the potential effects of NSS on rats ingesting MSG. To achieve this aim, adult male albino rats were randomly equally assigned into three groups for 21 days: control group received no treatment, MSG group received MSG as 30 g/kg feed, and MSG + NSS group received MSG as 30 g/kg and NSS as 30 g/kg feed. Testis histomorphometry showed marked deterioration by MSG as atrophic seminiferous tubules with degeneration of their lining cells, damaged Leydig cells and decreased germ cells number. Periodic Acid Schiff stain indicated irregular interrupted basement membranes. Glutathione reductase, superoxide dismutase 2 (SOD2), and caspase-3 immuno-expressions increased in testicular cells. Testosterone levels were significantly decreased in MSG challenged rats along with significant increase in luteinizing hormone levels, whereas NSS normalized this hormonal profile. MSG exposure also caused significantly increased lipid peroxides (LPO), glutathione-S-transferase, and total antioxidant capacity (TAC) whereas nitric oxide and SOD2 were significantly decreased. NSS succeeded in rebalance LPO and TAC and ameliorated the histoarchitectural disturbances. NSS mitigated MSG-induced testicular impairment by its antioxidant and cytoprotective activities.

“…Due to their polar nature, different solvents may give varied oil yields when using the solvent extraction process. Oil extraction solvents such as hexane, propane, ethane, tetrahydrofuran (THF), ethanol, dichloromethane, methanol, and the methanol-water binary system were all widely employed (Haile et al, 2019;Zhang et al, 2019;Alrashidi et al, 2020). Even if there is great purity and high oil production by utilising solvent, there is still energy squandered throughout the lengthy extraction process.…”

“…Another study used a solvent extraction approach on Calophyllum Inophyllum feedstock and found that extraction using solvent (hexane) yielded the best yield of 86.4%, outperforming mechanical screw presses (Bhuiya et al, 2020). Alrashidi et al (Alrashidi et al, 2020) tested the Soxhlet extraction technique for Nigella sativa L seed using several solvents. The results demonstrate that employing ethanol as a solvent yields the maximum oil yield (40.2%), whereas the methanol-water combination yields the lowest oil yield (28.3%).…”

This article looks at the national and global actors, social networks, and narratives that have influenced Jatropha’s worldwide acceptability as a biofuel crop. Jatropha Curcas is a genus of around 175 succulent shrubs and trees in the Euphorbiaceae family (some of which are deciduous, such as Jatropha Curcas L.). It’s a drought-tolerant perennial that thrives in poor or marginal soil and produces a large amount of oil per hectare. It is easy to grow, has a fast growth rate, and can generate seeds for up to 50 years. Jatropha Curcas has been developed as a unique and promising tropical plant for augmenting renewable energy sources due to its various benefits. It is deserving of being recognised as the only competitor in terms of concrete and intangible environmental advantages. Jatropha Curcas is a low-cost biodiesel feedstock with good fuel properties and more oil than other species. It is a non-edible oilseed feedstock. Thus it will have no impact on food prices or the food vs fuel debate. Jatropha Curcas emits fewer pollutants than diesel and may be used in diesel engines with equivalent performance. Jatropha Curcas also makes a substantial contribution to the betterment of rural life. The plant may also provide up to 40% oil yield per seed based on weight. This study looks at the features characteristics of Jatropha Curcas as biodiesel feedstock and performance, and emissions of internal combustion engine that operates on this biodiesel fuel.

“…In addition, cold pressing [ 4 ], supercritical fluid extraction [ 5 ], and ultrasonic/microwave-assisted extraction [ 6 ] are also widely used in the extraction of seed oil. Alrashidi et al [ 7 ] found that the Soxhlet method had a higher oil yield than cold pressing in Al-Qassim nigella oil. Zhang et al [ 8 ] found that different extraction methods significantly affected milk thistle seed oils’ minor component content and antioxidant activity.…”

Field muskmelon seed oil was extracted by press extraction (PE), Soxhlet extraction (SE), organic extraction (OSE), and aqueous extraction (AE). The oils were then evaluated for their physicochemical properties, fatty acid composition, volatile compounds, and antioxidant properties. A high yield oil was found in the SE sample. The AE sample had the highest elevated acid and peroxide values, while PE and OSE had the highest oil iodine content. The oil samples did not differ significantly in their fatty acid profile depending on the extraction method. However, E-nose, HS-GC-IMS, and HS-SPME-GC-MS showed that the flavor composition of the four samples was significantly different, attributed to the changes in the composition and content of the compounds caused by the different extraction methods. Furthermore, the strongest FRAP and the free radical scavenging ability of DPPH and ABTS+ showed in the SE sample. In general, SE’s seed oil has certain advantages when applied to the muskmelon seed oil industry.
