M. Sm (Zingiberaceae) 353 362 EN Behnam Mahdavi Department of Chemistry, Faculty of Science, Hakim Sabzevari University, Sabzevar, Iran Majid Mohammadhosseini Department of Chemistry, College of Basic Sciences, Shahrood Branch, Islamic Azad University, Shahrood, Iran|Nanotechnology Research Center, Islamic Azad University, South Tehran Branch, Tehran, Iran Journal Article 2022 12 01 The current report concerns with phytochemical and biological analysis of the organic extracts with different polarities, e.g., methanol, ethanol, ethyl acetate and acetone from some organs of Etlingera velutina (Ridl.) R. M. Sm (leaves, rhizomes and stems). This study revealed remarkable antioxidant potentialities of the prepared extracts using DPPH and β-carotene bleaching (BCB) assays as well as notable antibacterial features using disc diffusion and minimum inhibitory concentration methods. More importantly, the antiproliferative of methanolic extracts of the plant parts was evaluated against human prostate adenocarcinoma cell line using MTT assay.
