Abstract

|
The aim of this study was to evaluate the in vivo effect of galangin and the 70% ethanolic extract of Alpinia officinarum (AO) toward -induced DNA and chromosomal damage in mice. Galangin and AO inhibited the formation of 8-hydroxy-2’-deoxyguanosine (8-OH2’dG) as an indicator of DNA oxidative damage in the liver cell. Galangin and AO showed the inhibitory effect on the formation of DNA single strand break in the splenocyte by single cell gel electrophoresis (SCGE) assay and also inhibited micronucleated reticulocyte (MNRET) formation of peripheral blood in tail blood of mice. Vit-E revealed antigenotoxic effects in DNA and chromosome levels, but galangin was more potent active compound compare to vit-E under our experimental conditions. The results suggest that the extract of Alpinia officinarum containing galangin can modify the oxidative DNA and chromosomal damage and may act as chemopreventive agent against oxidative stress in vivo.
