Fifty percent (IC50) reduction of tumor cell viability was observed at a concentrations rate 100 - 320μg B /ml medium for HeLa cells and 320- 1000μg B /ml medium for MCF7 cells treated for 48 and 72 hours with B - phenolic fractions from the representatives of different populations raised in Bulgaria.	cache/american_scientific_journal-4877.pdf	txt/american_scientific_journal-4877.txt
