Medicinal Foodstuffs. VIII. Fenugreek Seed.(2) : Structures of Six New Furostanol Saponins, Trigoneosides IVa, Va, Vb, VI, VIIb, and VIIIb, from the Seeds of Indian Trigonella foenum-graecum L.
Following the characterization of trigoneosides Ia, Ib, IIa, IIb, IIIa, and IIIb, seven new steroidal saponins called trigoneosides IVa, Va, Vb, VI, VIIb, VIIIb, and IX were isolated from a medicinal foodstuff fenugreek seed, the seeds of Trigonella foenum-graecum L. (Leguminosae) originating from India. The structures of trigoneosides IVa, Va, Vb, VI, VIIb, and VIIIb were elucidated on the basis of chemical and physicochemical evidence.
