چکیده

karyotypes of eleven iranian populations of trigonella foenum-graceum were investigated. somatic chromosome numbers of examined populations were determined as 2n = 14. chromosomal parameters were examined as follows: long arm length (tl), short arm, total chromosome length, arm ratio, r-value, form percentage of chromosome, total form percentage of karyotype. chromosomes were mostly metacentric, but some submetacentric chromosomes were also observed. the genotypes number 3, 4, and 6 were classified into symmetric class of 2a and others stand to 1a. the results of analysis of variance based on completely randomized design (crd) showed a significant differences among the genotypes for all traits (p

Extraction of Fenugreek (Trigonella foenum-graceum L.) Seed Oil Using Subcritical Butane: Characterization and Process Optimization.

In this study, the subcritical butane extraction process of fenugreek seed oil was optimized using response surface methodology with a Box-Behnken design. The optimum conditions for extracted oil from fenugreek seed was as follows: extraction temperature of 43.24 °C , extraction time of 32.80 min, and particle size of 0.26 mm. No significant differences were found between the experimental and p...

Evaluation of antifertility activity of Trigonella foenum graecum seeds

Petroleum ether, ethanol and water extracts of Trigonella foenum graecum seeds were investigated separately to determine their antiimplantation (antifertility) and estrogenic/antiestrogenic activity in female albino rats and Swiss mice. Among these, ethanol extract was found to be the most effective as antiimplantation and estrogenic agent. In preliminary phytochemical screening, ethanol extrac...
