Five Steroidal Components from the Rhizomes of Polygonatum odoratum var. pluriflorum

Five steroidal components (PO-a(1)-PO-e(5)) were obtained from the methanolic extract or its partial hydrolysate of the fresh rhizomes of Polygonatum odoratum var.Pluriflorum, and their chemical structures were characterized as (25 R and S)-spirost-5-en-3β,14α-diol, 3-O-β-D-glucopyranosyl-(1->2)-3)>-β-D-glucopyranosyl-(1->4)-β-D-galactopyranosyl(=β-lycotetraosyl)-(25 R and S)-spirost-5-en-3β,14α-diol, 3-O-β-lycotetraosyl-22-methoxy-(25 R and S)-furost-5-en-3β,14α,26-triol 26-O-β-D-glucopyranoside, 3-O-β-D-glucopyranosyl-(1->2)-3)>-β-D-glucopyranosyl(1->4)-β-D-galactopyranosyl-22-methoxy-(25 R and S)-furost-5-en-3β,14α,26-triol 26-O-β-D-glucopyranoside and 3-O-β-lycotetraosyl yamogenin, respectively.Moreover, (25 S)-spirost-5-en-3β,14α-diol (7) was isolated from a mixture of the (25 R) and (S) derivatives of PO-a (1) and it was designated as neoprazerigenin A.Keywords - Polygonatum odoratum var. pluriflorum; Liliaceae; neoprazerigenin A; spirostanol glycoside; furostanol glycoside.
