Chinese quince (Chaenomeles sinensis) is used in food and pharmaceutical products, but it is seldom eaten as a raw fruit due to its astringent, woody flesh. The structural characterization of lignin fractions from Chinese quince was very important to investigate the structure-activity relationships of lignin. In this investigation, to characterize the structure of lignin in Chinese quince fruit...

The purpose of the study is to formulate and evaluate a new, cheap and effective natural mucoadhesive agent that can be used as an effective alternative for traditional mucoadhesive agent. The study procedure involved extraction of mucoadhesive agent from the Trigonellafoenumgraecum (fenugreek) seeds, solubility testing of the mucilage obtained, phytochemical testing, determination of swelling ...

Bittercress (Cardamine hirsuta) and mouse ear cress (Arabidopsis thaliana) both produce siliques that are morphologically similar to each other: a long cylindrical silique composed of two fused carpels. Despite this external similarity, the bittercress capsules have the ability to discharge their seed explosively, whereas the siliques of mouse ear cress only crack open along the suture lines to...

BACKGROUND Marine snow (small amorphous aggregates with colloidal properties) is present in all oceans of the world. Surface water warming and the consequent increase of water column stability can favour the coalescence of marine snow into marine mucilage, large marine aggregates representing an ephemeral and extreme habitat. Marine mucilage characterize aquatic systems with altered environment...

Chia seed mucilage represents an emerging resource in food industry due to its particular tetrasaccharide (repeating unit) composition. In this investigation, we report on the effect of biomacromolecule concentration and ageing structural integrity chia mucilage-based hydrogel networks. Hydrogels were produced with different polymer analyzed as prepared after 10 days ageing. Structural studies ...

SO4 has been used to investigate the production of extracellular mucilage by log-phase cells. Uptake of isotope occurs most rapidly in the light, when cells are actively dividing. The mucilage comprises about 50 % carbohydrate, 16% protein and 10 % sulphate. The major sugar is xylose; uronic acid, a small amount of galactose, glucose (trace) and 2 reducing substances are also present. Methylati...

The seed coat is important for embryo protection, seed hydration, and dispersal. Seed coat composition is also of interest to the agricultural sector, since it impacts the nutritional value for humans and livestock alike. Although some seed coat genes have been identified, the developmental pathways controlling seed coat development are not completely elucidated, and a global genetic program as...

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...
