Background: isolation and identification of some potent anti-tumor compounds from medicinal plants, has motivated researchers to screen different parts of plant species for anti-tumor effects.
It has been reported that several conifers posses cytotoxic activities on some human tumor cell lines Methods: in this study male and female branchlets or fruits of two different species of Iranian conifers were collected from the northern parts of Iran and identified. Hydroalcoholic extracts of them were prepared by perculation. The cytotoxic effects of the extracts on three human tumor cell lines [Hela, KB, and MDA-MB-468] were determined. Different concentrations of extracts were added to cultured cells and incubated for 72 h. Cell survival was evaluated using MTT-based cytotoxicity assay. Cytotoxicity was considered when mor than 50% decrese was seen in cell survival
Results: although the extracts from Platycladus orientalis significantly decreased Hela and MDA-MB-468 cell curvival, their effects were not considerable. Extracts from fruit and branchlets of male and female Juniperus sabina showed cytotoxic activities against Hela and MDA-MB-468 cells Conclusion: it is concluded that extracts of J. sabin have cytotoxic effects on cancer cells
