- Allium porrum; chemical structure; fractionation; spectral analysis; steroid saponins
- Abstract:
- ... A new steroidal glycoside (1) was isolated by fractionation of total extracted substances from Allium porrum. Its structure was determined as (25R)-5α-spirostan-3β,6β-diol-12-one 3-O-β-D-glucopyranosyl-(1→2)-[β-D-fucopyranosyl-(1→3)]-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside using chemical transformations, physical constants, and spectral data. ...

- Abstract:
- ... New steroidal glycoside 1 was isolated by fractionating total extracted substances from Allium porrum. Its structure was determined as (25R)-5_-spirostane-3β,6β-diol-2,12-dione 3-O-{β-D-glucopyranosyl-(1→3)-β-D-glucopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucopyranosyl-(1→4)-β-Dgalactopyranoside} using chemical transformations, physical constants, and spectral data. ...

- Abstract:
- ... New steroidal glycoside 1 was isolated by fractionation of total extracted compounds from rhizomes of Polygonatum verticillatum (Convallariaceae). Chemical transformations, physical constants, and spectral data characterized its structure as (25S)-spirost-5-en-3β-ol 3-O-β-D-glucopyranosyl-(1→3)-[β-Dfucopyranosyl-(1→2)]-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside. ...

- Abstract:
- ... Four known (1, 2, 4, and 5) and two new (3 and 6) steroidal glycosides were isolated from Polygonatum glaberrimum K. Koch (Convallariaceae) rhizomes by fractionation of the total extracted compounds. Their structures were determined as (25R)-spirost-5-en-3β,17α-diol 3-O-[α-L-rhamnopyranosyl-(1→2)]-β-Dglucopyranosyl-(1→4)- β-D-xylopyranoside (3) and 26-O-β-D-glucopyranosyl-(25R)-furost-5-en-3β,17α, ...

- Abstract:
- ... Two known (1 and 2) and two new (3 and 4) bisdesmoside cycloartane glycosides were isolated by fractionation of total extracted compounds from rhizomes of Euphorbia boissierana Prokh. (Euphorbiaceae). Chemical transformations, physical constants, and spectral data characterized the new glycosides as 3-O-β-D-(2′-OAc)-xylopyranosyl-6-O-β-D-xylopyranosyl-3β,6α,16β,24(R),25-pentahydroxycycloartane (3) ...

- Abstract:
- ... Two new steroidal glycosides were isolated by fractionation of total extracted substances from inflorescences and flower stalks of Allium rotundum (Alliaceae). The structures were determined on the basis of chemical transformations, physical constants, and spectral data as 26-O-β-D-glucopyranosyl-(25R)-5α-furostan2α,3β,22α,26-tetraol 3-O-β-D-glucopyranosyl-(1âââ2)[β-D-xylopyranosyl-(1 ...
