Rhapontica uniflora, Platycodon grandiflorum and Solanum tuberosum extracts affected the recovery of radiation-induced damage at all tested doses $(15.6,;31.3,;62.5;and;125;{mu}g/ml)$. The survival rate of pretreatment with extracts was increased by 2 times more than its compared with untreated cells. All tested extracts protected the growh-delay of normal cells and haematological parameters from their radiation-induced fall. In tested extracts, Solanum tuberosum was significantly superior to Platycodon grandiflorum and Rhapontica uniflora in radio-protection activity.
