| Popis: | Three new furostanol oligoglycosides, 3-O-{α-l-rhamnopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→4)]-β-d-glucopyranosyl}-26-O-β-d-glucopyranosyl-22α-methoxy-25R-furost-5-ene-3β,17α,26-triol (1), 3-O-{α-l-rhamnopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→4)]-β-d-glucopyranosyl}-26-O-β-d-glucopyranosylfurost-5-ene-3β,17α,22α,25,26-pentol (2), and 3-O-{α-l-rhamnopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→4)]-β-d-glucopyranosyl}-26-O-β-d-glucopyranosylfurost-5-ene-3β,22α,25,26-tetrol (3), named lycianthosides A−C, together with known flavone glycosides were isolated from Lycianthes synanthera leaves, an edible plant of the Solanaceae family that grows naturally in Guatemala. The nutrient composition of the raw leaves was also evaluated. Keywords: Lycianthes synanthera; Solanaceae; leaves; furostanol saponins; lycianthosides A−C, 1D and 2D NMR spectroscopy; flavone glycosides; nutrient composition |
