متن کاملHydroxyproline Glycosides in Secretory Arabinogalactan-Protein of Phaseolus vulgaris L.
The carbohydrate moiety of secretory arabinogalactan protein in bean seedlings (Phaseolus vulgaris L. cv. Prélude) is attached to the peptide backbone through hydroxyproline, serine, and threonine. Hydroxyproline-linked side chains, consisting of arabinose, galactose, glucose, and rhamnose, comprise the major part of the sugar residues. These hydroxyproline glycosides differ from those in non-e...
متن کاملTwo new cycloartane glycosides from the underground parts of Aquilegia vulgaris.
Two new cycloartane glycosides, named aquilegiosides K and L, have been isolated from the dried underground parts of Aquilegia vulgaris. Their structures were determined by two dimensional (2D) NMR spectroscopic analysis and chemical evidence.
متن کاملCytotoxic Flavonoid Glycosides from Rapistrum rugosum L.
Five flavonoid glycosides were isolated from the n-butanol soluble fraction of the ethanolic extract of Rapistrum rugosum and their structures were assigned from 1H- and 13C-NMR spectra (DEPT) with 2D NMR as quercetin-3-O-α-L-rhamnopyranoside (1), quercetin-3-O-β-D-xyloside (2), quercetin, 3-O-α-L-arabinopyranoside,7-O-α-L-rhamnopyranoside (3), kaempferol 3-O-α-L-arabinopyranoside, 7-O-α-L-rham...
متن کاملFlavonoid Glycosides from Tribulus terrestris L. orientalis
Tribulus terrestris L. var. orientalis (Kerner) G. Beck is widely used in the traditional medicine of many countries. Several flavonoides are identified from the plant material. Aerial parts which collected from northeast of Iran are used in this study. Three flavonoid glycosides were isolated and characterized. The flovonoids were found to be based on quercetin...
