Introduction Fenugreek, scientifically known as Trigonella foenumgraecum, which is a diploid annual legume belongs to Leguminosae family. From the age s fenugreek seeds are used as a spice and its aerial parts are used majorly as in form of vegetable, forage and some in dried leaves form. Fenugreek is beneficial to help in digestion and also helps in altering the food. According to various past researches it has been proven that fenugreek can be included in our daily diet 57. The medicinal usage of fenugreek was quite known in different forms as it is advisable to consume fenugreek seed for the treatment of kaph phlegm and vat wind which is related to digestive and respiratory problems and it is possible due to its aphrodisiac properties. But among all these parts, the fenugreek seed has the highest nutritional value like hypolipidemic effects 31 , antipyretic effects and antiinflammatory 19 , hypoglycaemia and antioxidant properties 35. Along with this fenugreek seeds are also rich in the

The leguminous family of plants includes fenugreek (Trigonella foenum-graecum L.), one of the oldest and most promising therapeutic herbs. Fenugreek is a member of the Fabaceae family. The goal of the current study was to evaluate the proximate composition, mineral analysis, phytochemical analysis and antioxidant potency of fenugreek seeds belonging to variety Hisar Mukta (HM) 425. The moisture content (%), crude protein (%), crude fat (%), ash (%), crude fiber (%), total carbohydrates (%) and mineral content (ppm) in fenugreek seeds were evaluated. The acetone extract of seeds was examined for a number of phytochemicals, including total phenolics (1.35 mg GAE/g), total flavonoids (0.12 mg CE/g), total sugars (17.34 mg/g), non-reducing sugars (17.18 mg/g) and reducing sugars (0.16 mg/g). The antioxidant activity was evaluated using the DPPH free radical scavenging activity and the phosphomolybdenum assay. These findings support the notion that fenugreek seeds are an abundant source of phytochemicals and minerals with pharmacological and health benefits.
Characterization of Fenugreek (Trigonella foenum-graecum) Seed Lipids
Journal of the American Oil Chemists' Society, 2011
The composition and content of lipids, fatty acids, triacylglycerols, tocopherols and sterols in nine fenugreek genotypes were analyzed. Lipid content in fenugreek seeds ranged from 5.8 to 15.2%. Major fatty acids were: linoleic acid (45.1-47.5%), a-linolenic (18.3-22.8%), oleic (12.4-17.0%), palmitic (9.8-11.2%) and stearic (3.8-4.2%) acids. The ratios of n-6 to n-3 fatty acids were between 2.1 and 2.7. Similar fatty acid distribution was observed in all analyzed samples with some deviations. a-Tocopherol was the predominant component found in the fenugreek lipid antioxidants, and it constituted over 84% of the total amounts of tocopherols. It amounts ranged from 620 to 910 mg/kg lipids. b-Sitosterol was the major sterol in all samples, varying from 14,203 to 18,833 mg/kg of lipids. Campesterol and cycloartenol were other major sterols, and these compounds including b-sitosterol constituted 56-72% of all sterols. Fenugreek seed lipids consisted predominantly triunsaturated (56.9-66.5%) and diunsaturated (32.2-41.6%) triacylglycerides. Among these components trilinolein (LLL; 12.9-20.5%) dominated followed by PLL (14.0-20.4%), LnLnO (7.8-17.7%), PLO (5.7-11.6%), OLL (6.9-10.6%), LLLn (3.2-9.6%), and LnLnL (3.5-7.6%). Results of the study show that fenugreek seed lipids may be a source of a nutraceutical ingredient for food applications.
Improvement in the nutraceutical properties of fenugreek ( Trigonella foenum-graecum L . )

Technol., 2006, 28(Suppl. 1) : 1-9 Fenugreek (Trigonella foenum-graecum L.) leaves and seeds have been used extensively for medicinal purposes. Fenugreek seed is known to exhibit anti-diabetic and anti-nociceptive properties and effects such as hypocholesterolaemic, anti-cancer and thyroxine-induced hyperglycaemia. Our research objectives have been to identify the chemical constituent(s) responsible for the health effects in human and to develop a strategy for improving these constituents in fenugreek plants. We have observed considerable variability among fenugreek genotypes. They differ in morphology, growth habit, biomass and seed production capability. Chemical constituents of the seed, e.g. saponins, fibre, protein, amino acids and fatty acid contents also differ markedly. This variability is most often ...

Fenugreek (Trigonella foenum-graecum L.), popularly known as methi, is a Leguminosae plant with many pharmacological and pharmaceutical benefits. Traditionally, it is used in Ayurveda, Chinese and Arabic systems of medicine. Fenugreek leaves, seeds, and oil has the potential to cure a variety of malady or illness such as gastric ulcer, gout, epilepsy, piles, chronic cough, bronchitis, and arthritis. Some research findings suggest that fenugreek seeds possess antioxidant, anti-inflammatory, antipyretic, antitumor, antimicrobial, and antidiabetic activity. Fenugreek seeds contain various essential phytoconstituents which are responsible for the pharmacological effects. The goal of this study is to explain the preliminary phytochemical standard of fenugreek seeds with powder microscopy and LCMS analysis.

Qualitative and Quantitative Estimation of Phytoconstituents in Trigonella Foenum Graceum
Fenugreek (Trigonella foenum-graecum) is an important spice; its dried seeds have wide application in food and beverages as a flavoring additive as well as in medicines. The objective of the present study was to evaluate the phytochemical constitution of ethanolic extract of dried plant parts (Leaf, Stem, Root and Seed) of Medicinal Herb Trigonella foenum-graecum. Qualitative and Quantitative analysis of phytochemical constituents' viz. Carbohydrate, Starch, Amino Acid, Protein, Lipid, Chlorophyll, Phenol and Alkaloid was performed by well-known test protocols available in the literature. Maximum amount of phytoconstituents was recorded in root part of plant. The results suggest that Trigonella foenum-graecum is a promising potential source of natural drug.
While the seeds of Trigonella foenum-graecum (L.) are relatively widely used as a spice and seasoning in food and as a traditional herbal medicinal product, those of T. caerulea have a more limited use and are rather ignored. We report on a comparative study of the surface morphology (investigated by scanning electron microscopy), of alcoholic extracts prepared from the seeds of the two species (analysed through HPLC) and of their fatty acid composition (investigated through GC, after derivatization with methanol). There are important differences in the seed morphology, the epidermis cells (macrosclereids) of T. foenum-graecum seeds are very narrow (6.4 x 8.4 μm; SD 0.8 μm and 0.8 μm) and those of T. caerulea are still narrower (4.4 x 5.2 μm; SD 0.6 and 0.5 μm, respectively). The HPLC chromatograms of the alcoholic seed extracts from the two species revealed at least seven peaks specific for T. foenum-graecum only, and three for T. caerulea only, suggesting a different chemical comp...
Analysis of Phytoconstituent Profile of Fenugreek – Trigonella Foenuem-Graecum L. – Seed Extracts
Studia Universitatis Babeș-Bolyai Chemia, 2017
Fenugreek (Trigonella foenum-graecum L.) is a well-known herb for its efficiency in the prevention/treatment of diabetes among other chronic diseases. The aim of present study was to analyse the phytoconstituent profile of aqueous and hydro-alcoholic extracts of fenugreek seeds produced in Hungary. The aqueous and hydro-aqueous extracts were analysed using a UHPLC-ESI-MS approach, and in the first 54, while in the second extract 67 phytoconstituents were identified that mostly corroborate the previously described health promoting effects of fenugreek. However, it remains a huge challenge to correlate the phytoconstituent composition of the two extracts with the generated dose dependent hormetic response and cytotoxic effects that were reported by us in case of some human breast cancerous cell lines.

Trigonella foenum-graecum L. (Fenugreek) commonly known as methi (in Hindi) has been used as a culinary spice, a flavoring agent and as a medicinal plant from ancient time. The present study comprises physicochemical and phytochemical evaluation of different extracts of Trigonella foenum-graecum. The physico chemical evaluation was carried out by the determination of ash values, extractive values and moisture content. Whereas phytochemical evaluation was carried out to estimate the presence of carbohydrates, glycosides, flavonoids, tannins, phytosterols and phenolic compounds in different extracts of Trigonella foenum-graecum. Results revealed the presence of carbohydrates, proteins, alkaloids, saponons, tannins, phytosterols, flavonoids, glycosides, fats and phenolic compounds. The present study will helpful in determining the quality and purity of a crude drug.
