Steroidal saponins from the rhizomes of Polygonatum prattii.
Seven steroidal saponins including two new furostanol glycosides were isolated from the rhizomes of Polygonatum prattii collected from Panzhihua, Sichuan province of China. The new compounds were determined as 26-O-β-d-glucopyranosyl-(25R)-3β,22ξ-dihydroxy-furost-5-en-7-one (pratioside G) and 26-O-β-D-glucopyranosyl-(25R)-22ξ-hydroxy-furost-5-en-3β-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside (pratioside H), on the basis of detailed spectroscopic and chemical analysis.
