Arabidopsis (Arabidopsis thaliana) epidermal seed coat cells follow a complex developmental program where, following fertilization, cells of the ovule outer integument differentiate into a unique cell type. Two hallmarks of these cells are the production of a doughnut-shaped apoplastic pocket filled with pectinaceous mucilage and the columella, a thick secondary cell wall. Cellulose is thought ...

The present investigation reports the isolation of mucilage from Manilkara zapota seeds as per AOAC guideline and evaluating it as mucoadhesive agent. Manilkara zapota (Linn.) P. Royen syn. a small tree belonging to family sapotaceae. Physiochemical characteristics of mucilage, such as swelling index, microbial count, viscosity, hydration capacity, flow property, and pH were studied. The mucila...

Mucilage of Plantago ovata husk has various characteristics like binding, gelling, granulating, film former, disintegrating, suspending, and sustaining properties and could be utilized for the preparation of pharmaceutical dosage forms like tablets, suspensions, gel and for sustained drug release systems. The present paper deals with the spectrophotometric estimation of total polysaccharide con...

BACKGROUND Mucilage compounds are pharmaceutically important polysaccharides that have an extensive range of applications, including binding agents, thickeners, water retention agents, emulsion stabilizers, suspending agents, disintegrates, film formers, and gelling agents. A historical approach to medical science written by Iranian scholars could help in identifying excellent ideas and provide...

Differentiation of the maternally derived seed coat epidermal cells into mucilage secretory cells is a common adaptation in angiosperms. Recent studies identified cellulose as an important component of seed mucilage in various species. Cellulose is deposited as a set of rays that radiate from the seed upon mucilage extrusion, serving to anchor the pectic component of seed mucilage to the seed s...

Seeds from the myxospermous species Plantago ovata release a polysaccharide-rich mucilage upon contact with water. This seed coat derived mucilage is composed predominantly of heteroxylan (HX) and is utilized as a gluten-free dietary fiber supplement to promote human colorectal health. In this study, a gamma-irradiated P. ovata population was generated and screened using histological stains and...

      The present study was performed to explore the matrix property of Ficus glomerata fruit mucilage for making transdermal patches. The mucilage was evaluated for its physicochemical properties. Various transdermal patches of indomethacin were prepared by solvent evaporation technique using different proportions of F. glomerata fruit mucilage. The compatib...

Hydrated Arabidopsis thaliana seeds are coated by a gelatinous layer called mucilage, which is mainly composed of cell wall polysaccharides. Since mucilage is rich in pectin, its architecture can be visualized with the ruthenium red (RR) dye. We screened the seeds of around 280 Arabidopsis natural accessions for variation in mucilage structure, and identified a large number of novel variants th...

During differentiation, the Arabidopsis (Arabidopsis thaliana) seed coat epidermal cells secrete mucilage composed primarily of rhamnogalacturonan I that is extruded from the seed coat upon imbibition. The mucilage of the mucilage modified1 (mum1) mutant contains rhamnogalacturonan I that is more highly branched and lacks the ability to be extruded when exposed to water. Our cloning of the MUM1...

A representative mucilage, named Hibiscus-mucilage SF, was isolated from the white flower buds of Hibiscus syriacus L. It was homogeneous on electrophoresis and gel chromatography. Its intrinsic viscosity value in aqueous solution was 26.0. It is mainly composed of partially acetylated acidic polysaccharide of molecular weight 1050000, and is composed of L-rhamnose : D-galactose: D-galacturonic...
