Chemical Composition of Astragalus: Carbohydrates and Mucilage Content
نویسنده
چکیده
This study was conducted to determine the content of carbohydrates and mucilage in roots and leaflets of different Astragalus species for the first time from Iran. The content of reducing sugars, oligosaccharides and polysaccharides in roots of the species were determined spectrophotometrically. The content and sugar composition of the mucilages in leaflets was determined by gravimetry and gas-liquid chromatography, respectively. According to the results of this research, the content of sugars in roots and mucilage in leaflets depends on the factors such as the species and geographical location of the plants. Reducing sugars, oligosaccharides and polysaccharides content in roots of the species varied from 0.11-0.90, 2.21-7.27 and 1.3-7.33% dry weight, respectively. The mucilage content in leaflets of different species varied from 5.32 to19.24% dry weight.

“Sticky invasion” – the physical properties of Plantago lanceolata L. seed mucilage
The mucilage envelope of seeds has various functions including the provision of different ways for the dispersal of diaspores. Chemical composition and water content of the mucilage yield particular adhesive and frictional properties in the envelope that also influence the dispersal of seeds. To determine the physical properties of Plantago lanceolata seed mucilage we studied (1) composition, (...
متن کاملArabidopsis Seed Coat Mucilage is a Specialized Cell Wall that Can be Used as a Model for Genetic Analysis of Plant Cell Wall Structure and Function
Arabidopsis seed coat epidermal cells produce a large quantity of mucilage that is extruded upon exposure to water. Chemical analyses and cell biological techniques suggest that this mucilage represents a specialized type of secondary cell wall composed primarily of pectin with lesser amounts of cellulose and xyloglucan. Once extruded, the mucilage capsule has a distinctive structure with an ou...
