Extraction, optimization and characterization of crude polysaccharides from Artemesia Mongolica
In this study, the extraction conditions of polysaccharides of Artemisia mongolia (PAM) were optimized and their molecular weight, weight distribution, composition and antioxidant activities of the polysaccharides investigated. The degree of polymerization of fructan-oligosaccharides 2-8 was separated by thin layer chromatography (TLC) with good results. Polysaccharides were extracted from the leaves of A. mongolia and...

Effect of pre-harvest chitosan foliar application on growth, yield and chemical composition of Washington navel orange trees grown in two different regions
The present study was carried out during 2012 and 2013 seasons to study the effect of pre-harvest foliar application of chitosan (a natural beta-1-4-linked glucosamine polymer) at two concentrations 250 and 500 ppm on vegetative tree growth, fruit yield and quality as well as leaves chemical composition of Washington navel orange trees grown under two locations. As for growth parameters (shoot length, leaves...
