Polysaccharide mucilage derived from the seeds of Ocimum basilicum L. (family Lamiaceae) was investigated for use in matrix formulations containing propranolol hydrochloride. Basil mucilage was extracted and several tablets were formulated. The effect of mucilage on drug release rate was evaluated in comparison with tablets containing two kinds of hydroxypropyl methylcellulose (HPMC K4M and HPM...

Interactions between cell wall polymers are critical for establishing cell wall integrity and cell-cell adhesion. Here, we exploit the Arabidopsis (Arabidopsis thaliana) seed coat mucilage system to examine cell wall polymer interactions. On hydration, seeds release an adherent mucilage layer strongly attached to the seed in addition to a nonadherent layer that can be removed by gentle agitatio...

Many sandy beach surf-zones support characteristic accumulations of diatom cells appearing as dark brown patches at the water surface. These diatoms become buoyant during the day, adhering to air bubbles generated by wave action. This, together with water circulation patterns generated by rip currents results in the accumulation of diatoms. By late afternoon the cells lose buoyancy and the accu...

Imbibed seeds of the Arabidopsis thaliana accession Djarly are affected in mucilage release from seed coat epidermal cells. The impaired locus was identified as a pectin methylesterase inhibitor gene, PECTIN METHYLESTERASE INHIBITOR6 (PMEI6), specifically expressed in seed coat epidermal cells at the time when mucilage polysaccharides are accumulated. This spatio-temporal regulation appears to ...

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...
