A new furostane-type steroidal glycoside and derivative of tigogenin (1) was isolated from aqueous wastes from production of the cardiac drug acetyldigitoxin from leaves of Digitalis ciliata Trautv. (Scrophulariaceae) and characterized. The structure of the glycoside was established using physical constants, chemical
transformations, and spectral data as 3-O-β-D-glucopyranosyl-(1→3) [β-D-fucopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-β-D-galactopyranosyl-(25R)-5α-furostan-3β,22α,26-triol-26-O-β-D-glucopyranoside. 相似文献

Background
A fermented beverage of plant extracts was prepared from about fifty kinds of vegetables and fruits. Natural fermentation was carried out mainly by lactic acid bacteria (Leuconostoc spp.) and yeast (Zygosaccharomyces spp. and Pichia spp.). We have previously examined the preparation of novel four trisaccharides from the beverage: O-β-D-fructopyranosyl-(2->6)-O-β-D-glucopyranosyl-(1->3)-D-glucopyranose, O-β-D-fructopyranosyl-(2->6)-O-[β-D-glucopyranosyl-(1->3)]-D-glucopyranose, O-β-D-glucopyranosyl-(1->1)-O-β-D-fructofuranosyl-(2<->1)-α-D-glucopyranoside and O-β-D-galactopyranosyl-(1->1)-O-β-D-fructofuranosyl-(2<->1)- α-D-glucopyranoside. 相似文献14.

A capsular polysaccharide (CPS) containing D-galactosamine uronic acid and D-alanine was isolated from a culture of the marine
proteobacterium Microbulbifer sp. KMM 6242. 2D NMR spectroscopy showed that the CPS is a homopolymer of 2-acetamido-2-deoxy-N-(D-galacturonyl)-D-alanine with the structure →4)-β-D-GalpNAcA6(D-Ala)-(1→. An O-specific polysaccharide containing D-ribose
and D-galactose was isolated from the cell-membrane lipopolysaccharide. 1D and 2D NMR spectroscopy established the structure
of the disaccharide repeating unit of the polysaccharide as →3)-β-D-Ribf-(1→4)-β-D-Galp-(1→. 相似文献

2-Aminoethyl glycoside of the hexasaccharide chain of ganglioside Fuc-GM1 was synthesized by a [3+3] synthetic scheme. At the key step of the synthetic route, glycosylation of the only hydroxyl group
at C(4) of the galactose residue in an α-(N-acetylneuraminyl)-(2→3)-β-D-galactopyranosyl-(1→4)-β-D-glucopyranoside derivative
with a peracetylated thioglycoside of α-L-fucopyranosyl-(1→2)-β-D-galactopyranosyl-(1→3)-2-trichloroacetamido-2-deoxy-β-D-galactopyranose
gave a protected hexasaccharide in high yield. Subsequent removal of the protecting groups gave the target 2-aminoethyl glycoside
of the oligosaccharide chain of gan-glioside Fuc-GM1.
