Steroidal alkaloid saponins and steroidal saponins from Solanum surattense

Phytochemistry, 2011
A rare 16β-H steroidal alkaloid saponin (1), an avenacoside-type saponin (2), two steroidal saponins (4, 5), one revised-structure steroidal saponin (3) and six known compounds (6-11) were isolated from aerial parts of Solanum surattense Burm. f. Their structures were established on the basis of physical data, as well as by using spectroscopic (HRESIMS,

Steroidal saponins from Smilacina japonica

Fitoterapia, 2012
Three new steroidal saponins, japonicoside A (1), japonicoside B (2) and japonicoside C (3) were isolated from the dried rhizomes and roots of Smilacina japonica A. Gray. Their structures were elucidated as (25S)-5α-spirostan-9(11)-en-3β-ol 3-O-β-D-glucopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside (1), (25S ...

Steroidal saponins from Dioscorea preussii

Fitoterapia, 2014
Three new steroidal saponins, named diospreussinosides A-C (1-3), along with two known ones (4, 5) were isolated from rhizomes of Dioscorea preussii. Their structures were elucidated mainly by 1D and 2D NMR spectroscopic analysis and mass spectrometry as (25S)-17α,25-dihydroxyspirost-5-en-3β-yl-O-α-L-rhamnopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→4)-β-D ...

Steroid saponins from Solanum laxum

Phytochemistry, 1996
Two new steroid saponins, named laxumins A and B, were isolated from the ethanolic extract of the aerial parts of Solanum laxum. These compounds were characterized, using mainly NMR spectroscopy, mass spectrometry and chemical methods, as (23S,25S)-spirost-5-en-3 beta, 15 alpha, 23-triol 3-O-{beta-D-glucopyranosyl-(1-->2)- beta-D-glucopyranosyl-(1-->4)-

Steroidal saponins from Smilax lebrunii

Phytochemistry, 1992
Two new steroidal saponins, (25 R)-spirostan-3 beta-ol-6-one-3-O-[alpha-L-arabinopyranosyl (1----6)]-beta-D-glucopyranoside and (25 R)-spirostan-3 beta-ol-6-one-3-O-[beta-D-glucopyranosyl(1---4)] [alpha-L-arabinopyranosyl(1----6)]-beta-glucopyranoside, were isolated from the rhizomes of Smilax lebrunii.

Steroidal Saponins in Oat Bran

Journal of Agricultural and Food Chemistry, 2016
Saponins are one type of widespread defense compound in the plant kingdom and have been exploited for the production of lead compounds with diverse pharmacological properties in drug discovery. Oats contain two unique steroidal saponins, avenacoside A, 1, and avenacoside B, 2.

Steroidal saponins from Chlorophytum deistelianum

Planta Medica, 2016
Phytochemical investigation of the aerial parts of Chlorophytum deistelianum led to the isolation of four previously undescribed steroidal saponins called chlorodeistelianosides A-D with five known ones. Their structures were established mainly by extensive 1D and 2D NMR spectroscopic techniques and mass spectrometry as (25R)-3β-[(β-D-glucopyranosyl-(1→
