The protective role of leaf antioxidant systems in the mechanism of plant acclimation to growth irradiance was studied in Vinca major, Schefflera arboricola, and Mahonia repens, which were grown for several months at 20, 100, and 1200 [mu]mol photons m-2 s-1. As growth irradiance increased, several
The aim of this study was to examine the cytotoxic and genotoxic potential of a hydroethanolic extract of Schefflera vinosa (SV), a plant with schistosomicidal activity, as well as its influence on DNA damage induced by different mutagens, methyl methane sulfonate (MMS) and hydrogen peroxide (H2O2),
This study investigated various biological activities of the ethanolic extract of dried ground leaves of Schefflera leucantha Viguier (Araliaceae). The extract possessed very low cytotoxicity to brine-shrimp with the LC(50) of 4,111.15 microg/ml; the significant antioxidant activity on DPPH with the
Recent studies have revealed that dietary flavonoids are potent radical scavengers, acting in a manner similar to ascorbate and [alpha]-tocopherol. However, it is still not clear whether flavonoids have a similar antioxidative function in plants. We examined the possibility that flavonoids could
