Abstract
Millimolar concentrations of ascorbic acid or sodium ascorbate induced cytotoxicity against human glioblastoma T98G cells. Addition of hot w ater and sodium hydroxide extracts of the bark of Acer nikoense Maxim. synergistically enhanced the cytotoxic activity of ascorbate. Human p eripheral blood lymphocytes and polymorphonuclear cells were relativel y resistant to ascorbate, the Acer nikoense Maxim. extract, or a combi nation of them. The extracts stimulated the degradation of ascorbates via ascorbyl radical production, in parallel with their ability to sti mulate the cytotoxic activity of ascorbate. The results suggest the me dicinal efficacy of the Acer nikoense Maxim. extracts.
