Oligosaccharides ofSaponaria officinalis
ConclusionsIt has been found that the roots ofSaponaria officinalis L. contain three oligosaccharides.Two of them have been isolated: gentiobiose and the pentasaccharide saponarose. It has been shown that the latter is O-β-D-galactopyranosyl-(1 → 3)-O-α-D-galactopyranosyl-(1 → 3)-O-α-D-galactopyranosyl-(1 → 3)-O-α-D-galactopyranosyl-(1 → 1)-α-D-glucopyranoside.
Analysis of carbohydrates in Saponaria officinalis L. using GC/MS method
Saponaria officinalis L. (common soapwort), usually named fuller’s herb, is encountered in most of Europe, in Spain, France, Italy, for example, and also in Syria and North Africa. Saponaria officinalis L. is known in most of the world as an introduced species, often a weed, and sometimes as cultivated decorative plant. Saponaria officinalis contains a large amount of saponins, which foam during extraction with water. In addition to saponins, common soapwort also contains flavonoids, quillaic acid, fatty acids and different phenolic compounds. There is a lack of information about carbohydrates content of common soapwort. Thus the aim of this study was to determine the content of carbohydrates Saponaria officinalis L. herb and roots. The qualitative composition and quantitative content of carbohydrates in herb and roots of Saponaria officinalis L. were determined by using GC/MS method. The studies have shown that Saponaria officinalis L. herb is mainly composed of free carbohydrates such as D-glucose (3.65 mg/g), D-galactose (0.29 mg/g), D-fructose (0.20 mg/g) and D-saccharose (3.72 mg/g). In common soapwort herb, after acidic hydrolysis and derivatization with acetylated aldononitriles, D-arabinose, D-fucose, D-mannose, D-glucose, D-galactose, D-fructose and Myo-inositol were identified. Free carbohydrates in the roots of Saponaria officinalis L., including D-glucose, D-galactose and D-saccharose, were determined with GC/MS method too. D-saccharose was common among free carbohydrates of Saponaria officinalis L. in the largest amounts. Its content in herb and roots of the common soapwort was 3.72 mg/g and 25.39 mg/g respectively.
Ueber die Verbindungen der Zuckerarten mit den Mercaptanen
Die leichte Bildung der Alkoholglucoside1) legte den Gedanken nahe, ahnliche Derivate der Mercaptane aufzusuchen. Dieselben verbinden sich in der Tat unter dem Einflus von Sauren sehr leicht mit dem Traubenzucker und seinen Verwandten. Aber die Produkte sind anders zusammengesetzt als die Glucoside; sie enthalten auf ein Molekul Zucker zwei Molekule Thioalkohol und entsprechen mithin den Derivaten der gewohnlichen Aldehyde, welche Baumann Mercaptale2) genannt hat.
