Abstract

Extraction and purification matairesinol bioactive lignan of arizonica cypress (cupressus arizonica) A. Sedaghat1, A. Abdulkhani 2 1. M. Sc, Department of wood and paper science, Faculty of Natural resources, University of Tehran 2. Assistant Professor, Department of wood and paper science, Faculty of Natural resources, University of Tehran Matairesinol lignan (MR) of arizonica cypress was isolated, characterized and purified. Isolated was made using a hexane pretreatment for removing the lipophilic moieties followed by an ethanol-water (9:1 v/v) treatment by soaking the wood flour in the solvents. Also matairesinol, was purified with potassium acetate. Identification of extracts were performed in all stages by means of gas chromatography- mass spectrometry (GC/MS). Results showed that amount of MR lignan in the original ethanol extract, sediment and clear solution after centrifugation was 11.3, 32.59 and 40.44% respectively.... ...... .... .... .... .. ..... .... .... ... .......................................................................................................................... ......... .............................. ..... ......................................................................................................
