Key Word Index - Trigonella foenum-graecum; Leguminosae; fenugreek; furostanol glycosides, trigofoenosides A and D. - Two new furostanol glycosides trigofoenosides A and D have been isolated from the Trigonella foenum-graecum seed as their methyl esters, A-1 and D-1.Their structures have been determined as (25S)-22-O-methylfurost-5-ene-3β,26-diol, 3-O-α-L-rhamnopyranosyl(1 - 2)-β-D-glucopyranoside; 26-O-β-D-glucopyranoside (A-1) and (25S)-22-O-methyl-furost-5-ene-3β,26-diol, 3-O-α-L-rhamnopyranosyl (1 - 2)-<β-D-glucopyranosyl ( 1 - 3)>-β-D-glucopyranoside; 26-O-β-D-glucopyranoside (D-1).
