Determination of Steroidal Saponins and Fixed Oil Content in Fenugreek (Trigonella foenum-graecum) Genotypes

Trigonella foenum-graecum, commonly called fenugreek, is a leguminous plant native to many Asian, Middle Eastern and European countries. Fenugreek oil is very effective in digestion. Identification of fenugreek genotype rich in saponins and fixed oil will be useful for pharmaceutical industries. In the present study, steroidal saponin and fixed oil content was analysed in 46 diverse fenugreek genotypes on dry weight basis. Significant differences were observed in the total saponin and fixed oil content among the genotypes. Saponin and fixed oil content ranged from 0.92 g to 1.68 g and 3.25 to 6.88 g with corresponding mean value of 1.34 g and 5.19 g/100 g dw, respectively.
