Bioactive Compounds from Natural Sources: Isolation Corrado Tringali, Ebooks Corporation.
Publisher: CRC Press

Extraction of bioactive compounds with potential applications in pharmacology and biomedicine is a relatively new trend in microalgal biotechnology. Magnolol is a bioactive compound isolated from the bark of M. In addition, our laboratory has demonstrated the anti-diabetic effect of two natural compounds from Radix Astragali, astragaloside II and isoastragaloside I, which can enhance the expression of adiponectin, an insulin-sensitizing adipokine [17]. The present study also aims at isolation of new natural antimicrobial compounds from some selected plants through bioassay guided isolation. Andrey has always been interested in renewable resources, so wood chemistry studies were a natural choice for him. Nature has been a source of medicinal agents for thousands of years and an impressive number of modern drugs have been isolated from natural sources, many of which are based on their uses in traditional medicine. For bio-autography, the coloured NATURAL SCIENCES, Analytical chemistry, Microbiology, 4. Stages necessary to concentrate toxic cyanobacteria for the isolation of known cyanotoxins or natural products of unknown or uncertain toxicity, and subsequent extraction, isolation and purification of cyanotoxins for sale or for their own research programs. Seaweeds are important sources of carotenoids, and numerous studies have shown the beneficial effects of these pigments on human health. This study aims to isolate bioactive ingredients from the traditional Chinese herb Radix Astragali (Huangqi) that alleviate obesity-induced metabolic damage through inhibiting inflammation. Cyanobacteria are rich sources of novel bioactive compounds, many of which are poorly researched with respect to toxicity [2]. In the present study, Himanthalia The separated compounds were tested for their potential antioxidant capacity and antimicrobial activity against Listeria monocytogenes bacteria using TLC bioautography approach. Officinalis that has been used in Asian traditional medicine for the treatment of anxiety, sleep disorders, and allergic diseases. A growing number of marine microorganisms are the sources of novel and potentially life-saving bioactive secondary metabolites. There are several familiar approaches for lead searching from the plants and the isolated bioactive compounds are utilized in three basic ways (Cox, P.A., 1994): Unmodified natural plant products where .. The objective is to develop a series of consecutive extractions for wood fractionation into its main polymeric compounds: hemicellulose, lignin and cellulose using water as solvent as well as suitable additives. Hemicelluloses have also bioactive properties, so they can be used as a food additive or even in pharmaceuticals” explains Andrey.
