Trichloroethylene (TCE) is a chlorinated organic pollutant of groundwater with diverse toxic effects in animals and humans. Here, we investigated the ameliorative role of hesperidin, a citrus bioflavonoid on TCE-induced toxicity in Drosophila melanogaster. Four groups of D. melanogaster (50 flies/vial, with 5 vials/group) were exposed to ethanol (2.5%, control), HSP (400 mg/10 g diet), TCE (10 μM/10 g diet) and TCE (10 μM/10 g diet) + HSP (400 mg/10 g diet) respectively in the diet for 5 days. Then, selected oxidative stress and antioxidant markers were evaluated. The results showed that TCE significantly increased the level of reactive oxygen species (ROS) and inhibited catalase, glutathione S-transferase and acetylcholinesterase (AChE) activities with concurrent depletion of total thiol level. However, co-administration of TCE and hesperidin mitigated TCE-induced depletion of antioxidants, and restored ROS level and AChE activity in the flies (p < 0.05). Overall, hesperidin offered protective potency on TCE-induced oxidative stress in the flies via anti-oxidative mechanism.
