Abstract
Two new furostane saponins named hamoside A and B were isolated from the 80% ethanolic extract of the defatted seeds of Trigonella hamosa L. On the basis of chemical evidence and spectral analysis (IR, 1H NMR, 13C NMR, HSQC, HMBC and positive ion MS), hamoside A (1) was established as (22ξ)-2α, 3β, 26-triol-3-O-β-D-galactopyranosyl-(1→4)-O-β-D-glucopyranosyl-(1→2)-O-α-rhamnopyranosyl-(1→4)-O-β-D-xylopyranoside-furost-5-ene, and hamoside B (2) as (22ξ)-2α, 3β, 26-triol-3-O-β-D-galactopyranosyl-(1→4)-O-β-D-glucopyranosyl-(1→4)-O-β-D-xylopyranoside-furost-5-ene.
