title: Cytostatic activity of peptide extracts of medicinal plants on transformed A549, H1299, and HeLa Cells.
abstract: Biological activity of peptide extracts of medicinal plants was studied on transformed non-small-cell lung carcinoma A549 cells, lung cancer H1299 cells, and cervical cancer HeLa cells at various cell densities. Cell survival and proliferation were evaluated 72 h after treatment with extracts in concentrations of 0.05, 0.25, and 0.5 microg/microl. The cytostatic effect was produced by peptide extracts of Camelia sinesis Kuntze, Inonotus obliquus, and a mixture Inula helenium L., Chelidonium majus L., Equisetum arvense L., and Inonotus obliquus. Peptide extracts of Hypericum perforatum L. and Laurus nobilis L. in the same concentrations had no effects on proliferative activity and growth of tumor cells.
