Evaluating the cytotoxicity of extracts were done by MTT assay against HT-29, KATO-III, and HUVEC cell lines. The extract with The most cytotoxicity on cancer cells and lower toxicity on normal cell line was subjected to the fractionation by MPLC using a RP-18 silica gel column and in the next stage and the cytotoxicity of resulted fractions were determined by MTT assay.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Chloroform: methanol extract was the safest extract on HUVEC cells with great cytotoxic effects against cancer cell lines (IC50 17.3 and 23 \u00b5g\/mL, for KATO-III and HT-29, respectively). The results of MTT assay for 7 fractions of the chloroform: methanol extract showed that 5\n th<\/jats:sup>\n fraction (E) was the most cytotoxic fraction (IC50 9 and 11.2 \u00b5g\/mL for HT-29 and KATO-III, respectively).
