Drug delivery via buccal mucosa by means of buccoadhesive formulations offer distinct advantages over peroral administration. Recently, plant gums and exudates have been screened for their use as pharmaceutical adjuvants. The aim of this study is to evaluate matrix tablets containing Plantago psyllium seed mucilage in addition to carbopol as a mucoadhesive agent, and propranolol hydrochloride a...

Purpose. The study reports evaluation of different purification processes for removing surplus surfactant and formulating stable nanoparticle dispersions. Methods. Nanoparticle formulations prepared from poly(D,L-lactide-co-glycolide) and polyvinyl alcohol (PVA) were purified by a diafiltration centrifugal device (DCD), using 300K and 100K molecular weight cut-off (MWCO) membranes and a tangent...

Cactus is a plant that naturally grows in tropical and semi-tropical regions of the world. The composition of this mucilage is believed to differ from species to species. Hence, comparative study was carried out on mucilages of Opuntia ficus-indica (OFI) and Opuntia stricta (OS) as regard to their physico-chemical properties and acute toxicity levels. The study indicated that solubility of the ...

The main objective of the present study was to develop matrix-moderated transdermal systems of Diltiazem HCl using various proportions of Ficus reticuleta fruit mucilage. Physical evaluation was performed such as moisture content, moisture uptake, tensile strength, flatness and folding endurance. In-vitro penetration studies were performed in a Keshary-Chien diffusion cell. The matrix-type tran...

An increasing interest in the use of natural polymers or gums in pharmaceutical formulations focusing the tremendous orientation to discover and extract such gums. The pharmaceutical industry is ever thirsty to satisfy patient’s therapeutic needs by utilizing inactive excipients along with active ingredients in formulation development. Binders are added to tablet formulations to add cohesivenes...

A silica-supported CdS nanoparticle photocatalyst exhibits excellent visible-light driven H2 evolution activity without the use of a cocatalyst. The apparent quantum yield can reach 42% under 420 nm light illumination.

Tamarind seed polysaccharide (TSP) obtained from the seed kernel of Tamarindus indica, possesses properties like high viscosity mucilage, broad pH tolerance, no carcinogenicity, mucoadhesive nature, and biocompatibility. It is used as stabilizer, thickener, gelling agent, and binder in food and pharmaceutical industries. The objective of present investigation was to search for a cheap and effec...

3,4-dihydropyrimidin-2(1H)-thiones were synthesized in the presence of Ag nanoparticle/melamine sulfonic acid (MSA) supported on silica gel. The reaction was carried out at 110 oC for 20 min under solvent free conditions. In all cases, the three component reaction proceeded smoothly to give the corresponding 3,4-dihydropyrimidin-2(1H)-thiones in moderate to good yield. We have found the best co...

Coffee pulp, mucilage, and beans with mucilage were used to develop alcoholic beverages. The pulp of 45.3% 54.7% seed, 9.4% only obtained during the wet processing coffee. Musts prepared for all TSS (Total soluble solid) 18 °Bx fermentation was carried out 12–16 days until decreased 5 at 30 °C. Phenolic characteristics, chromatic structures, chemical parameters, sensory characteristics analyzed...
