JORDAN, M. S. & W. J. HAYDEN (1992). A Survey of Mucilaginous Testa in Chamaesyce. Collect. Bot. (Barcelona) 21 :79-89. Seeds of Chamaesyce were studied for presence of mucilaginous testa. Samples were selected to represent all major systematic sections within the genus. Observations were made with a dissecting microscope following brief hydration of seeds; additional SEM observations of both i...

Pectins are major components of plant primary cell walls. They include homogalacturonans (HGs), which are the most abundant pectin and can be the target of apoplastic enzymes like pectin methylesterases (PMEs) that control their methylesterification level. Several PMEs are expressed in the seed coat of Arabidopsis thaliana, particularly in mucilage secretory cells (MSCs). On the basis of public...

BACKGROUND The dilution and rapid elimination of topically applied drugs due to the flushing action of saliva is a major difficulty in the effort to eradicate infections of oral cavity. Utilization a proper delivery system for incorporation of drugs has a major impact on drug delivery and such a system should be formulated for prolonged drug retention in oral cavity. OBJECTIVES The aim of the...

Opuntia dillenii (Ker Gawl.) Haw., a well-known member of the Cactaceae family, played an important role in agriculture and medicine. In this study, extraction conditions physico-chemical properties water-soluble polysaccharides (OMP) from mucilage were investigated. The cactus cladodes used study collected Binh Thuan province, Vietnam. optimum water with conventional heating included at temper...

Carrageenin is the water soluble polysaccharide extractable from the red algae Chondrus crispus and Gigartina stellata. The polysaccharide is essentially a polymer of alpha-D-galactopyranoside-4-sulphate. Smith et al. (1954) fractionated carrageenin with potassium chloride into two components and obtained a precipitable component which could form gels and a nongelling component which remained i...

A microwave assisted extraction technique was developed to optimize the extraction of mucilage from the fruits of Abelmoschus esculentus plant. The plant has been extracted by conventional and microwave assisted methods for the isolation of mucilage. Microwave extraction at 160 W intensity and 40 min heating duration increase 11.55% in the yield of mucilage when compared to 1 h conventional hea...

Plant cells are encased within a complex polysaccharide wall that strengthens the cell and has key roles in all aspects of plant cell growth, differentiation, and interaction with the environment. This dynamic structure is under continual modification during plant development, and its synthesis and modification require the activity of a myriad of enzymes. The mucilage secretory cells (MSCs) of ...

lallemantia royleana (balangu) is a well known iranian medicinal plant that its seed mucilage has many applications in modern pharmacology. plant mucilage traditionally was used as a gel supplement, and natural matrix for sustained release of drugs. but it seems that these compounds are not a simple additive and also have many undiscovered pharmacological properties. in this research, the anest...

The function of a putative galacturonosyltransferase from Arabidopsis (Arabidopsis thaliana; At1g02720; GALACTURONOSYLTRANSFERASE-LIKE5 [AtGATL5]) was studied using a combination of molecular genetic, chemical, and immunological approaches. AtGATL5 is expressed in all plant tissues, with highest expression levels in siliques 7 DPA. Furthermore, its expression is positively regulated by several ...

A binder holds powders together to form granules and also provides the cohesiveness required for binding of the granules under compression to form a tablet. Some natural excipients are currently available for pharmaceutical formulation. Aim of this study was to isolate the mucilage from different plants and to evaluate them as a binder. Here an effort was made to investigate the efficacy of muc...
