Abstract
An investigation of the composition of two varieties ofLupinus termis seeds showed the presence of proteins, free amino acids, lipids, lignin, polysaccharides and mannitol. The polysaccharide materials (27.47 – 34.33%) consisted of starch, combined galacturonic acid, galactose, arabinose, xylose and rhamnose. Combined galactose and rhamnose comprised the major components of polysaccharide materials. Protein's constituted 46.11 – 50.57% ofL. termis seeds. The amino acid composition of the seeds as well as those of the proteins isolated with different agents were determined. The amino acid patterns of free and combined amino acids varied according to the extracting agent.
Résumé
Une recherche de la composition des deux variétés des grains duLupinus termis montre la presence des protéines, acides aminés libres, lipides, lignin, polysaccharides et le mannitol. Les polysaccharides (24.47 – 34.33%) se composent de starch, acide galacturonique combiné, galactose, arabinose, xylose et rhamnose. Galactose et rhamnose combinés forment la majorité de la constitution des materiels polysaccharides. Les protéines ont formé 46.11 – 50.57% de grains duLupinus termis. La composition des acides aminés des grains, aussi bien que celle des protéines isolés par plusieurs agents ont été déterminés. Les cadres d'acide aminé des acides libres et combinés ont été variés selon l'emploi de l'agent d'extraction.
Zusammenfassung
Eine Untersuchung der Samen zweierLupinus termis Sorten ergab die Anwesenheit von Proteinen, freien Aminosäuren, Lipiden, Lignin, Polysacchariden und Mannit. Die Polysaccharid-Fraktion (27,47 – 34,33%) besteht aus Stärke, gebundener Galakturonsäure, Galaktose, Arabinose, Xylose und Rhamnose. Die gebundene Galaktose und Rhamnose bilden die Hauptbestandteile der Polysaccharide. Die Proteine machen 46,11 – 50,57% derL. termis Samen aus.
Es wurde sowohl die Aminosäurenzusammensetzung der Samen bestimmt als auch die der mit verschiedenen Agentien isolierten Proteine. Die Aminosäurenmuster der freien und gebundenen Aminosäuren variieren je nach dem Extraktionsmittel.
