Research ArticleOpen accessIn the keywordsEXTRACTION 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 · 8,612 accessesView PDFCite
