Research ArticleOpen accessIn the abstractEXTRACTION OF QUERCETIN FROM POLYGONUM HYDROPIPER L. BY SUBCRITICAL WATERA. V. Lekar, S. N. Borisenko, E. V. Vetrova et al.The new method of quercetin extraction from Polygonum hydropiper L. by subcritical water was developed. High performance liquid chromatography was used for identification and quantification of flavonoids in the extract. The new method is environmentally friendly and more effective (7.6-times) than traditional flavonoids extraction methods using expensive and toxic organic solvents. …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 23 Nov 2013 · 8,614 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiocontrol of Botrytis allii Munn the Causal Agent of Neck Rot, the Post Harvest Disease in Onion, by use of a New Iranian Isolate of StreptomycesM. Jorjandi, G.H. Shahidi Bonjar, A. Baghizadeh et al.Problem statement: Soil actinomycetes particularly Streptomyces spp. have showed antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. Onion neck rot or gray mold caused by Botrytis allii have imposed economic post harvest damages to onion bulbs and decreased its storage durability and market value. Approach: To investigate for … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,942 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExtraction of Genomic DNA Using Magnetic Nanoparticles (Fe3O4) as a Solid-Phase SupportZ. M. Saiyed, C. N. RamchandMagnetic separation technology, using magnetic particles, is quick and easy method for sensitive and reliable captures of specific proteins, genetic material and other biomolecules. The current paper describes a universal genomic DNA extraction method optimized in our laboratory using magnetic nanoparticles as a solid phase adsorbent. The yields of the isolated DNA with magnetic method were higher or equivalent to … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 9,831 accessesView PDF Cite
