Astaxanthin, a member of the carotenoid family, is a dark-red pigment which is the main carotenoid found in the marine world of algae and aquatic animals. Astaxanthin, is present in many types of seafood, including salmon, trout, red sea bream, shrimp and lobster, as well as in birds such as flamingo and quail. Synthetic Astaxanthin dominates the world market but recent interest in natural sources...
Chitosan a natural polymer available and easy to produce in countless parts of the world; is a material that can significantly improve the standard of living in developing countries where the industry is often surpassing the need to protect the environment and/or where the environment protection is strongly dependent on limited financial resources available to those in charge of environmental prot...
Extensive research has been carried out from last decades to discover potential constituents from plant sources. Stigmasterol is an important constituent and has been isolated from plants. It is involved in the synthesis of many hormones like progesterone, androgens, estrogens and corticoids. In addition to stigmasterol many of its derivatives like, spinasterol, fucosterol, cyasterone, stigmaste...
ANTIOXIDANT, ORGAN PROTECTIVE AND AMELIORATIVE PROPERTIES OF METHANOL EXTRACT OF ANOGEISSUS LEIOCARPUS STEM BARK AGAINST CARBON TETRACHLORIDE- INDUCED LIVER INJURY
The methanol extract of the stem bark of Anogeissus leiocarpus was evaluated in vivo at 2.5mg/kg for antioxidant, hepatoprotective and ameliorative effect on hepatocellular injury following pre-treatment or post-treatment with carbon tetrachloride (CCl4). Levels of the lipid peroxidation product, malondialdehyde (MDA) or thiobarbituric reactive substances (TBARS) were taken as a measure of oxidati...
Incorporation of drugs into non-ionic surfactant vesicles (niosomes) during their manufacture affords a possible method of achieving controlled release. The aim of this study is to formulate niosomes as carriers for delivery of diclofenac sodium (DCS). Niosomes are prepared with a series of sorbitan monoesters (Span 20, 40, 60, and 80) and sorbitan tri-oleate (Span 85) and co-surfactants of polyox...
Niosomes are self assembled vesicles composed primarily of synthetic surfactants and cholesterol. They are analogous in structure to the more widely studied liposomes formed from biologically derived phospholipids. Niosomes represent an emerging class of novel vesicular systems. Niosome formation requires the presence of a particular class of amphiphile and aqueous solvent. In recent years a compr...
Oral drug delivery remains the preferred route of drug delivery. Novel technologies with improved performance, patient compliance, and enhanced quality have emerged in the recent past. The fast dissolving drug delivery system started gaining popularity and acceptance as a new drug delivery system because they are easy to administer and lead to better patient compliance. Fast dissolving drug delive...
The use of herbal drugs for the prevention and treatment of various health ailments has been in practice from time immemorial. Acacia arabica has been reported to be effective against a variety of disease including diabetes, skin disease and most concerning with cancer. The fresh plants parts of Acacia arabica is considered as astringent, demulcent, aphrodisiac, anthelmintic, antimicrobial, anti...
A SIMPLE UV SPECTROPHOTOMETRIC METHOD FOR THE DETERMINATION OF FEBUXOSTAT IN BULK AND PHARMACEUTICAL FORMULATIONS
A simple and cost effective spectrophotometric method is described for the determination of febuxostat in pure form and in pharmaceutical formulations. The drug was highly soluble in methanol so it was selected as the solvent system for the drug. This ensured adequate drug solubility and maximum assay sensitivity. The linearity range for febuxostat at its wavelength of detection of 315 nm was obta...
ANTIBACTERIAL, RADICAL- SCAVENGING ACTIVITIES AND CYTOTOXICITY PROPERTIES OF PHALERIA MACROCARPA (SCHEFF.) BOERL. LEAVES IN HEPG2 CELL LINES
Antibacterial, and radical scavenging activities of four crude extracts of Phaleria macrocarpa (Scheff) Boerl.) leaves extracts and its active crude cytotoxic properties in HepG2 cells were investigated. The susceptibility bacteria tests were performed by the Mueller Hinton agar well diffusion method. The Radical scavenging activity was measured by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method...
