| Abstract: | 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. |
