Plants gums are complex mixtures of different polysaccharides with a variety of biological activities and pharmaceutical applications. Few studies have focused on physicochemical and biological properties of gums obtained from different plants. This study was designed to determine potential pharmaceutical and pharmacological values of the gum exudates and its isolated biopolymers obtained from ...

This study examines the controlled release behavior of both water-soluble (acetaminophen, caffeine, theophylline and salicylic acid) and water insoluble (indomethacin) drugs derived from Caesalpinia pulcherrima seed Gum isolated from Caesalpinia pulcherrima kernel powder. It further investigates the effect of incorporating diluents such as microcrystalline cellulose and lactose on caffeine rele...

A water-soluble crude polysaccharide preparation (GFP) was obtained from Grifola frondosa fruit bodies by hot water (100 °C) extraction, followed by ethanol (75%) precipitation. Purified polysaccharides, GFP75-2D was obtained from the crude material by successive fractionation using DEAE-Sepharose Fast Flow ion exchange chromatography and Sephacryl S gel filtration chromatography. GFP75-2D main...

Two Bacillus species were studied which produced bioemulsifiers; however, they were distinctly different compounds. Bacillus sp. strain IAF 343 produced unusually high yields of extracellular biosurfactant when grown on a medium containing only water-soluble substrates. The yield of 1 g/liter was appreciably better than those of most of the biosurfactants reported previously. This neutral lipid...

Most of the natural polysaccharides have been used as food and pharmaceutical excipients due to their biodegradability, biocompatibility, low cost and easy availability. Diverse approaches such as etherification, crosslinking and graft co-polymerization can be used for the chemical modification of natural polymers. Grafting process is a suitable method to add new properties to a natural polymer...

UNLABELLED The red seaweed Phyllophora pseudoceranoides (Gmelin) New. et Tayl, commonly found in the Romanian Black Sea coastal waters, has not been studied regarding its chemical composition and biological activities. AIMS The aim of the present study was to isolate, characterize and assess the in vitro antioxidant activity of the crude polysaccharide from P. pseudocerano ides. MATERIALS A...
