Research ArticleOpen accessIn the abstractSensitization of Photohemolysis by a New Extraction from Flowers and Aerial Parts of Cichorium Pumilum Jacq: Effects of Inulin and Hydrogen PeroxideM-Ali H. Al-Akhras, Amr Amin, Karima Mohammad et al.Addition of inulin and hydrogen peroxide to new photosensitizers extracted from the flowers and aerial parts of the chicory (Cichorium Pumilum Jacq) have been investigated. Some of the isolated photosensitizers remain unidentified compounds. Chicory extracts are found to be dependent on light and temperature. Higher photohemolysis rate was noticed under the influence of light as compared to temperature. The effect … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 7,722 accessesView PDF Cite
