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-glucopyranoside; 26-O-β-D-glucopyranoside (D-1).

A new furostanol glucuronide and three known glycosides, SL-0, aspidistrin and methyl proto-aspidistrin, were isolated from the fresh immature berries of Solanum lyratum.The structure of the new compound was characterized as 26-O-β-D-glucopyranosyl-(22ξ,25R)-3β,22,26-trihydroxyfurost-5-ene 3-O-α-L-rhamnopyranosyl-(1 -> 2)- 3)>-β-D-glucopyranoside. Key Word Index - Solanum lyratum; Solanaceae; furostanol glucuronide.-24β-ethyl-5α-cholesta-7,trans-22,25(27)-trien-3β-ol; spinasteryl-β-D-glucopyranoside.
