Comparative analysis on bioactive compounds and antioxidant activity of Algerian fenugreek (Trigonella foenum-graecumL.) and Syrian cumin (Cuminum cyminumL.) seeds

Abstract

Summary Introduction: Natural products represent a gold mine for scientists looking for compounds for the treatment of health problems and diseases with their different biological and pharmacological activities. However, recent research is focused on finding natural sources of antioxidants. Objective: The objective of current research was to determine the phytochemical profile of Algerian fenu-greek (Trigonella foenum-graecum L.), and Syrian cumin (Cuminum cyminum L.) seeds in order to characterize their phenolic compounds and to determine their antioxidant activities. Methods: Total phenolic, flavonoids, condensed and hydrolysable tannins contents were quantified using Folin-Ciocalteu, aluminium chloride, vanillin and ferric chloride methods, respectively. Phenolic compounds were identified by HPLC method and antioxidant activity was measured using DPPH assay. Results: The higher amounts of total phenolic compounds, flavonoids, condensed and hydrolysable tannins were given by fenugreek. Results of HPLC analysis of our plants showed that eight phytochemical compounds were found in cumin extract, and seven molecules in fenugreek extract. Moreover, fenugreek possessed higher antioxidant activity. Conclusion: This study confirmed that our plants are a good source of phenolic contents and possess a high antioxidant activity.

Optimization of Aqueous Extraction of Polyphenols from Cuminum cyminum Seeds Using Response Surface Methodology and Assessment of Biological Activity

“…Rutin (0.1 ppm) and ellagic acid (3.78 ppm) were the two main polyphenols found in C. cyminum after water bath extraction by HPLC analysis. These findings are not in compliance with those reported by Bouhenni et al [50], where results of HPLC analysis of cumin seeds of Syrian origin extracted using 70% methanol as a solvent showed that eight phytochemical compounds were detected in cumin extract. This is mainly due to the different types of solvents used for the extraction.…”

Evaluation of Proximate, Phytochemical, and Heavy Metal Content in Black Cumin and Fenugreek Cultivated in Gamo Zone, Ethiopia

“…The flavonoid content in fenugreek from Daramalo was highest and from Kamba was lowest, but at the 0.05 level, the means were not significantly different (p = 0:18629, which was p > 0:05). The total average flavonoid content in fenugreek of this study was lower than the literature mean values (145 mg QE/100 g and 274 mg QE/100 g) reported by [40]. In general, the result of this study showed that black cumin and fenugreek cultivated in the Gamo zone were good sources of flavonoid compounds.…”

The Influence of Different Concentrations of Plant Hormones in Vitro on Seeds Germination of Fenugreek (Trigonella Foenum-Graecum)

“…Trigonella foenum-graecum has been used as a medicinal herb for a long time for many benefits known in traditional medicine. As a result, many studies have been conducted to clarify and prove the medicinal benefits of fenugreek [16], [17]. Seeds of fenugreek containing 25,5% protein, saponins 4.8 %, 20% mucous membranes substances, and 7,9% fat, young leaves and sprouts are a rich protein, mineral and vitamin C source.…”
