“…As shown in Table 2, the yield of TFC from fenugreek seeds was 2.3 (90%, 10 ml/g, 35 min, 300 W) –10.394 mg RE/g (62.5%, 35 ml/g, 55 min, 300 W) with rutin as the quantitative standard. The results were similar to the yield (1.03%) obtained by Yang Renming et al (Baba et al, 2018). However, both DPPH clearance rate (66.58%–89.35%) and the yield of flavonoids were significantly higher than the 6.76 mg quercetin equivalent (QE)/g dry weight (DW) (59.9%) reported by Qazi Tabasum et al, and the results obtained by Norziah, M. H et al (68%) using the Soxhlet extraction method (Norziah & Fezea, 2015).…”

Fenugreek seeds (Trigonella foenum‐graecum L.), one kind of traditional Chinese medicine, are reported to be of great potential as a new alternative in terms of their bioactive components. In our present study, an ultrasonic‐assisted method was applied in the extraction of antioxidative components from fenugreek seeds. Four factors: ethanol concentration, liquid–solid ratio, sonication time, and sonication power were selected and multiple responses were studied using the response surface methodology (RSM). The effects of factors along with the correlation between all responses (flavonoids content, 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) assay, OH− assay) were studied. The regression model indicated that all four factors are of significant effect on all responses. The model predicted that the ethanol concentration of 72%, solvent‐to‐material ratio of 35 ml/g, ultrasonic time of 41 min, and 500 W of power would provide a flavonoid yield of 9.10 mg/g, DPPH clearance of 80.33%, and OH− clearance of 24.28%, respectively. The confirmation test showed the closeness of the predicted results with those of experimental values. And AB‐8 resin was successfully used to purify the fenuellus hulusi seed extract, and the flavonoid concentration of 78.14% was obtained. Six flavonoids (Swertisin, Puerarin apioside, Jasminoside B, Astragalin, Apigenin‐7‐O‐beta‐D‐glucoside, and Apiin) were successfully identified by the liquid chromatography–mass spectrometry (LC–MS) analysis.

“…The total phenolic and flavonoid contents of the seeds were determined as 3.34±0.02 mg GAE/g seed and 0.96±0.09 mg QE/g seed, respectively. The total phenolic and flavonoid contents of 80% methanolic extracts of different Trigonella species (T. spruneriana, T. sibthorpii, T. kotschyi, T. mesopotamica, T. cylindricea, T. cilicica, T. filipes, T. velutina, T. strangulata, T. smyrnea, and T. rhytidocarpa) from Turkey have been studied previously and the results indicated that the total phenolic and flavonoid contents ranged from 35.47 to 201.35 mg GAE/g and 2.57-128.04 mg RE/g, respectively (Uras Güngör et al 2017;Güngör et al 2021) The total phenolic and flavonoid contents of methanolic extracts of T. foenum-graecum seeds from different geographical origins were in the range from 36.20-48.76 mg GAE/g and 2.73-4.76 mg QE/g, respectively (Pant et al 2017;Baba et al 2018).…”

The genus Trigonella (Fabaceae) has been widely used for both culinary and clinical purposes since ancient times. The aim of this study was to investigate the chemical composition and in vitro antioxidant activities of Trigonella cariensis seeds for the first time. The seeds were collected in the province of Mersin, Turkey. Chemical analyses were performed using chromatographic methods. Fatty acid, tocopherol and sterol analyses were done on hexane extracts and amino acid and mineral analyses were also carried out on the seeds. The total phenolic and flavonoid contents were measured by using the Folin-Ciocalteu and Al(NO3)3 methods and in vitro antioxidant activity was evaluated via different chemical assays including 1,1-diphenyl-2-picrylhydrazily (DPPH?), cupric reducing antioxidant power (CUPRAC) and 2,2?-azinobis(3-ethylbenzothiazoline)-6-sulphonate (ABTS?+) on its 80% methanolic extract. The seeds were shown to contain mainly linoleic, ?-linolenic and oleic acids (43.74?0.24%, 18.38?0.45%, and 10.89?0.71%, respectively). The seeds showed high ?-tocopherol content (233.54?2.48 mg/100 g). The main sterols were ?-sitosterol, delta-5-avenasterol and campesterol. Na, K, Ca, P, and Mg were the predominant minerals, while glutamic acid, aspartic acid and lysine (5801?0.15, 3629?0.12 and 2062?0.03 mg/100 g, respectively) were determined as the major amino acids in the seeds. The total phenolic and flavonoid contents were 3.34?0.02 mg GAE/g seed and 0.96?0.09 mg QE/g seed, respectively. The results of the ABTS?+, DPPH? and CUPRAC methods were 43.22?3.14%, 31.15?1.79% and 9.67?0.78 mM AAE/g, respectively. In conclusion, T. cariensis seeds provide nutritional value with a good source of polyunsaturated fatty acids, ?-tocopherol, ?-sitosterol, some amino acids and minerals and medicinal properties with total phenolic and flavonoid contents and antioxidant activities.

“…Fenugreek gum is also able in reducing blood glucose, improve insulin sensitivity, and regulate cholesterol levels in the liver [26]. In numerous studies, the researcher found that the fenugreek twig had significant antioxidant, antimicrobial, and DNA protective properties and was used as natural food additives [27].…”

Fenugreek seeds have widespread relations with Ayurveda, Unani, and Arabic medicine. The seeds were useful for the treatment and prevention of different ailments. Fenugreek (Trigonella foenum-graecum) or methi is from the Leguminosae family and are primarily known for its anti-diabetic and hypocholesterolemic activities. The germinated fenugreek seeds were used in the treatment of E.coli infection in Germany and France. The important phytoconstituents responsible for such medicinal applications are saponins, polyunsaturated fatty acids, galactomannans, trigonelline, and 4-hydroxy isoleucine. Flavonoids, apigenin 6,8-di-C-glucoside, apigenin-6-C-glucosyl-8-C-galactoside, 6-Cgalactosyl- 8-C-arabinoside are the chief ingredients of fenugreek seeds; responsible for reducing blood glucose while given to diabetic rats, whereas important flavones are epigenin, luteolin and vitexin. The other major bioactive components in fenugreek seeds are polyphenols like rhaponticin and isovitexin. Fenugreek seeds contain phosphorus and are categorized into different classes such as inorganic phosphorus, phospholipids, phytates, phosphor-proteins, and nucleic acid. Germinated seeds profusely filled with amino acids with amino acids, proteins, ascorbic acid, sugars. Further, this review shares information about the recent therapeutic intervention not covered earlier; on in vivo and in vitro and some clinical applications against certain interesting ailments other than older applications. This review includes certain nano delivery systems of Fenugreek seeds and their medicinal application.
