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...

Several compounds have been described as metabolites of nicotinic acid and nicotinamide in mammals. These are nicotinic acid (I), nicotinamide (2)) nicotinuric acid (2)) trigonelline (2)) W-methylnicotinamide (NMN) (3-6)) and 1-methyl-3-carboxylamide-6-pyridone (7, 8). According to the observations of various workers mammals may be divided into two groups in so far as the metabolism of nicotini...

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...

Natural excipients can serve as alternative to synthetic products because of local accessibility, biodegradability, eco-friendly nature and cost effectiveness as compared to synthetic products. Therefore, it is a current need to explore natural excipients that can be used as an effective alternative excipient for the formulation of pharmaceutical dosage forms. Adansonia digitata (Malvaceae) has...

The success of seedling establishment of desert plants is determined by seedling emergence response to an unpredictable precipitation regime. Sand burial is a crucial and frequent environmental stress that impacts seedling establishment on sand dunes. However, little is known about the ecological role of seed mucilage in seedling emergence in arid sandy environments. We hypothesized that seed m...

The concentration of glucan, mucilage, soluble carbohydrates, and malic acid were determined in Opuntia bigelovii Engelm. during a 23-week period. The experiment began during the dry summer by irrigation to stimulate Crassulacean acid metabolism and was followed by 13 weeks of drought. After the 13-week drought period, the plants were irrigated throughout a 10-week period until late December. T...

In the present work, fast disintegrating tablets of prochlorperazine maleate were designed with a view to enhance patient compliance by direct compression method. In this method mucilage of Plantago ovata and crospovidone were used as superdisintegrants (2-8% w/w) along with microcrystalline cellulose (20-60% w/w) and directly compressible mannitol (Pearlitol SD 200) to enhance mouth feel. The ...

Seven prenylated stilbenes were identified by combined HPLC-PAD-APCI/MSn analysis of an extract of mucilage isolated from peanut (Arachis hypogaea L.) root tips. The principal constituent was assigned the structure 4-(3-methyl-but-1-enyl)-3, 5-dimethoxy-4'-hydroxy-trans-stilbene. The common name mucilagin A is proposed for this novel compound. Its concentration in the mucilage was estimated at ...
