Medicinal plants are rich in secondary metabolites (alkoloids, glycosides, coumarins, flavonides, steroids, etc.) and considered to be more effective and a safer alternative source to manage a variety of diseases related to liver, heart and kidney disordered. This study determines in vitro antioxidant and in vivo toxicological profile including hemolytic, brine shrimp lethality and mutagenicity of aerial parts of Artemisia absinthium. DNA protection assay was performed on pUC19 plasmid vector

... ing H(2)O(2) as oxidative agent. Total phenolic and flavonoid content were determined using colorimetric methods. Toxicity of the plant was evaluated by brine shrimp lethality, hemolytic and mutagenic activity. DNA protection assay of the plant showed concentration dependent protective effect and at concentration 10μL/mL revealed complete protective effect against H(2)O(2) induced DNA damage. Highest phenolic and flavonoid content was found to be 167.3 (mg GAE 100g DW(-1)) and 14 (mg CE 100g DW(-1)) respectively. Results showed that A. absinthium is potent against standard toxicological procedures, that indicates the presence of bioactive components in the plant and possess antioxidant activity that protects DNA against H(2)O(2) induced oxidative damage. Thus the results showed/support that A. absinthium provides significant health benefits.
