Background: Wood vinegar (WV), a byproduct from the charcoal production process, has been reported to have excellent antioxidant capability by chemical examination. However, the biological effect of WV in living animals is still unknown. In this study, a simple model organism, the nematode Caenorhabditis elegans, was used as an in vivo system to assess the biological effects of wood vinegar through the development, lifespan, brood size, germline cell apoptosis and superoxide dismutase (SOD) level. Results: Wood vinegar extract (WVE) promoted the development, prolonged the lifespan and increased the brood size in reactive oxidative species (ROS)-sensitive mutant worms. WVE treatment rescued the effects of damage in germline cell apoptosis and SOD upregulation induced by paraquat, an ROS generator, to the control level. Additionally, WVE showed comparative ability in rescuing damage as compared with L-ascorbic acid and α-tocopherol. Conclusion: WVE treatment exhibits a remedial/beneficial effect on ROS-sensitive mutant under normal cultural conditions and on wild-type worms under oxidative stress. ROS scavenging is involved in the damage-rescuing mechanism. This study will provide a basal biological and nutritional exploration for the use of WV as a functional food, and for the substitution of chemical antioxidants with side effects in food. © 2011 Society of Chemical Industry.

To investigate effects of a mixture of bamboo powder including vinegar liquid (BV) supplementation on growth performance, meat quality and antioxidant property in broilers during fattening, 300 15 weeks old Wenchang broilers, a Chinese indigenous breed were randomly allotted to two treatments and fed the basal diet supplemented with 0.5% BV or not (control group). Each treatment includes three replicates of 50 birds fed. The experiment lasted for 3 weeks. Although, the weight gain was not significantly different, the growth performance tended to be improved in 0.5% BV supplemented group. Besides, drip loss and pH after 12hpost-mortem were significantly decreased (p<0.05). Total Antioxidant Capability (T-AOC) also showed obvious increase in breast muscle, heart, spleen and kidney (p<0.05). The results suggested that BV may act as a natural source of feed additive for broilers fattening. © Medwell Journals, 2011.
