In vitro cell-toxicity of Peganum harmala alkaloids on cancerous cell-lines.

ABSTRACT

The alkaloidic fraction of the methanol extract of Peganum harmala seeds was tested in vitro on three tumoral cell-lines UCP-Med and Med-mek carcinoma, and UCP-Med sarcoma. Proliferation was significantly reduced at all tested concentrations (20-120 micrograms/ml) during the first 24 h of contact. A cell lysis effect occurred after 24 h and increased thereafter to complete cell death within 48-72 h, depending on tested concentration.
