Phytochemical screening and pharmacological activities of the crude ethanolic extracts of Trigonella foenum-graecum L.
Main Article Content
Abstract
Trigonella foenum-graecum L., or fenugreek, is a plant belonging to the Fabaceae family. It has a history of being used in food and medicinal plants since ancient times. This study is a preliminary study on the phytochemicals and pharmacological activities of the Indian fenugreek seeds used in Thailand. The results showed that the ethanolic crude fenugreek seed extract had various phytochemicals such as phenolic compounds, saponins, and tannins. The concentration was 0.48±0.03 mg/mL of this crude extract, which inhibited 50% of the lipase enzyme but did not inhibit alpha-glucosidase and alpha-amylase. In addition, the concentration of crude extract of fenugreek seed was not toxic to RAW 264.7 macrophages, with survival percentages ranging from 93.90±2.11 to 110.37±2.75, and the crude extract of fenugreek seeds had anti-inflammatory effects by inhibiting nitric oxide formation. The crude extract suppressed nitric oxide generation in LPS-stimulated RAW 264.7 macrophages at concentrations of 0.01, 0.1, and 1 mg/mL, with no significant differences observed among these three doses (p>0.05). The inhibition percentages were 20.00±3.85, 25.16±2.58, and 24.30±3.94, respectively. The anti-inflammatory efficacy of the crude fenugreek seed extract was comparable to that of triamcinolone acetonide at concentrations of 0.01, 0.1, and 1 mg/mL, with no statistically significant differences (p>0.05). The data in this study indicate that the Indian fenugreek seeds used in Thailand can further develop as a medicinal or dietary supplement.
