Abstract Aim: In the past decades, nanotechnology has received much attention in order to develop new drug delivery systems to overcome the limitations of routine drugs in the treatment of diseases. Nanotechnology offers very useful applications in the diagnosis and treatment of cancer, as nanomaterials can penetrate into body tissues at the cellular and molecular levels.
Materials and methods: In the present study, samarium nanoparticles were synthesized by the extract of ginger using green chemistry synthesis method. The size of the synthesized nanoparticles was investigated by dynamic light scattering (DLS) technique and formation of new functional groups was investigated by FT_IR technique. The morphology of the nanoparticles was determined using FE-SEM scanning electron microscopy. Finally, the cytotoxicity and anticancer activity of samarium nanoparticles were studied against human colorectal cancer cell line of HCT116 after 24 and 48 hours incubation times using tetrazolium colorimetric assay (MTT assay).
Results: Dynamic light scattering data in agreement with Fe-SEM data revealed the formation of globular nanoparticles of 60 nm. Cell survival assay showed Ic50 values (the concentration of the compound that induces 50% death in cancer cells) of 90 (equal to 23.1 mg/ml) and 81 μM (equal to 20.7 mg/ml) of samarium nanoparticles on HCT116 cell line after 24 and 48 hours incubation times, respectively.
Conclusion: It is concluded that the newly green synthesized samarium nanoparticles with anticancer activity might be a good candidate for colon cancer therapy.

Abstract Aim: This investigation was conducted to determine the amount of isolated anthocyanins from seed coats of Phaseolus vulgaris L. under magnetic field treatment and also assess their antiproliferative activity of the extracts.
Material and method: Dry and soaked red bean seeds were subjected to different electromagnetic field treatments in four group. The seeds of groups 1(dry) and 2 (soaked) were treated for 45 min., while in groups 3 and 4 the dry and soaked seeds treated two times with 120 min. interval with electromagnetic field.   Then, they were cultured and grown, and their produced seeds were collected. Seed coats from these beans were separated and coat extract was prepared. Two groups of anthocyanins, cyanidin and pelargonidin, were identified and measured by high performance liquid chromatography (HPLC). The antiproliferative activity of the extract was determined by MTT assay against ovarian cancer cells (CP2780A).
Results: The bean coats of the control and the treated plants contain a high content of cyanidin and pelargonidin. Among the extracts, the samples of group 1 had the highest amount of cyanidin, while seeds of group 2 had the highest amount of pelargonidin. The results of the antiproliferative activity revealed that the methanol extract of the treated red beans under 4 mT were highly antiproliferative activity of the cell (78.74 to 84.44 %). Moreover, the seeds of group 2 showed the highest antiproliferative activity (IC₅₀: 72.63 ± 2.2).
Conclusion: The electromagnetic field treatment is the most effective in increasing the amounts of anthocyanins in red beans, and that the red bean coat can be used as a natural source of nutrition and drug supplement with antiproliferative properties.
