Effects cytotoxic and genotoxic of Psittacanthus acinarius and Psittacanthus cordatus (mistletoe) on Allium cepa

This study assessed the cytotoxic and genotoxic potentials of extracts Psittacanthus acinarius (Mart.) Mart. cordatus (Hoffmanns.) in root cell cycle Allium cepa L. Aqueous leaf P. at three concentrations: 0.00, 5 20 mg/mL for 24 hours. Histological slides were prepared mitotic indices (MI %) chromosomal alteration (CAI determined. Inhibitory effects aqueous extract leaves observed 46.33 46.00% concentrations mg/mL, respectively, relation to control (62.83%), addition a higher index by 0.26% concentration mg/mL. In cordatus, greatest inhibitory 33.83 35.50% (88.16%) highest (3.30%) The inhibit MI %, reveal an irregular recovery or prevent it, induce alterations, suggesting on division meristematic cells A. cepa.
