A new glycosylated triterpene has been isolated from the fruit of Blighia welwitschii. The structural analysis of its peracetylated derivative (1) was performed by 2D homonuclear and heteronuclear NMR spectroscopy. The saponin was shown to contain hederagenin and five sugar residues forming two glyc

β¦ Synopsis
High-resolution 2D 'H-n.m.r. spectroscopy has been used to establish the structure of an acetylated pentasaccharide saponin from the fruit of Blighia welwitschii as acetylated 3~-~-[~-D-Xylp-(1~3)-cY-I~-Arap-(l~4)-~-D-Glc~-(l~3)c-w-L-Rhap-(l-2)-cw-L-Araplhederagenin.

The composition and sequence of 2-acetamido-2-deoxy-beta-D-glucose (GlcNAc) and 2-amino-2-deoxy-beta-D-glucose (GlcN) residues in partially N-deacetylated chitosans, prepared under homogeneous and heterogeneous conditions, have been determined by 1H-n.m.r. spectroscopy. It was necessary to depolymer
In the food industry, a knowledge of the presence and proportions of certain sugars in vegetables is important. In seeking to ascertain the presence of sucrose, l-kestose (1, isokestose), and neokestose (2) in enriched mixtures extracted from vegetables without isolating the individual sugars, we ha
The combined use of thermal analysis (t.g.-d.t.a.) and 13C-n.m.r. spectroscopy allows one to identify four different structural environments for TPA + ions occluded in the ZSM-5 channels. A first low-temperature (ca. 380Β°C) d.t.a, peak is assigned to less strongly held or outer shell "strained" TPA
