Steroidal Saponins of Yucca schidigera Roezl.

Journal of Agricultural and Food Chemistry, 2001
Eight steroidal saponins have been isolated from Yucca schidigera Roezl. trunk, and their structures were established by spectral (MS and NMR) techniques. These included three novel furostanol glycosides including 3-O-beta-D-glucopyranosyl-(1-->2)-[beta-D-xylopyranosyl-(1-->3)]-beta-D-glucopyranosyl-5 beta(25R)-furostan-3 beta,22 alpha,26-triol 26-O ...

New steroidal saponins from Asparagus acutifolius

Planta Medica, 2006
Asparagus acutifolius L. belongs to the Liliaceae family in which the steroidal saponins are fairly widespread. A survey of the literature showed that several Asparagus species have already been chemically studied and found to contain bioactive steroidal saponins.

Steroidal saponins of Asparagus curillus

Phytochemistry, 1982
Abstract Three spirostanol and two furostanol glycosides were isolated from a methanol extract of the roots of Asparagus curillus and characterized as 3- O -[α- l -arabinopyranosyl (1→4)- β- d -glucopyranosyl]-(25 S )-5β-spirostan-3β-ol, 3- O -[{α- l -rhamnopyranosyl (1→2)} {α- l -arabinopyranosyl (1→4)}-β- d -glucopyranosyl]-(25 S )-5β-spirostan ...

Steroid saponins and steroid alkaloid saponins: pharmacological and biological properties

1995
A large number of steroid saponins and glycoalkaloids exhibit the foaming and haemolytic properties typical of saponins. They also share a large number of the biological activities of triterpene saponins, such as expectorant and diuretic effects. Furostanol glycosides are responsible for the bitter taste of asparagus (Kawano et al. 1975), tomato seed

Steroidal saponins from Allium waldsteinii

Chemistry of Natural Compounds, 2006
In continuation of studies of steroidal glycosides from plants of the genus Allium L. (Alliaceae, Liliaceae) in the flora of Georgia, we investigated the aerial part of A. waldsteinii Don. collected during flowering near Kodzhori. We established previously that the principal active substances from this species were steroidal compounds. We isolated from

Steroidal Saponin from Allium porrum

Chemistry of Natural Compounds, 2017
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.

Steroidal saponins of Asparagus adscendens

Phytochemistry, 1982
Abstract From the methanol extract of the fruits of Asparagus adscendens sitosterol-β- d -glucoside, two spirostanol glycosides (asparanin A and B) and two furostanol glycosides (asparoside A and B) were isolated and characterized as 3-O-[β- d -glucopyranosyl (1→2)-β- d -glucopyranosyl]-(25S)-5β-spirostan-3β-ol, 3-O-{[β- d -glucopyranosyl(1→2)][α- l -
