Antigenotoxic effect of plant extracts

This report reviews our study of antigenotoxic compounds from medicinal and aromatic plants performed over several years. The studies of this type are aimed at understanding the protective mechanisms which may be relevant for the primary prevention of cancer and other mutation-related diseases. Antigenotoxic potential in this study is estimated with prokaryotic and eukaryotic tests measuring spontaneous and induced mutations, recombination, mutagenic repair, chromosomal aberrations and micronuclei. Our results indicate that monoterpenoids from sage act as modulators of DNA repair pathways, whereas sage antioxidants interfere with metabolic activation enzymes. The potential use of sage extracts in cancer prevention is discussed.
