The Antioxidant Activities of Noni Complex Beverage and Its Potential Antialcoholic Effect in Mice

Alcoholic beverages are widely consumed around the world. However, excessive alcohol consumption is harmful to human health, which can cause a series of health problems. Herbals with antioxidant activity as antialcoholic agents have a long history in Asia. In this study, we made a Noni complex beverage (NCB) using Noni and nine other plant materials, which has a potential antialcoholic effect. The total flavonoid content (TFC) and total phenolic content (TPC) were analyzed, and then the antioxidant activities in vitro and antialcoholic effects in vivo were assessed. The results showed that NCB contains TFC of 0.543 ± 0.001 mg/mL and TPC of 1.685 ± 0.029 mg/mL, with significant antioxidant activity in vitro. Furthermore, NCB also showed a good antialcoholic effect in mice. Whether before or after alcohol intake, the consumption of NCB could significantly extend the drunken latency time, shorten the sobriety time, and decrease the blood alcohol concentration compared with the model group. Analysis of the antialcoholic mechanism demonstrated that NCB can remarkably increase the activity of superoxide dismutase, improve glutathione level, and reduce malondialdehyde content, thereby combating oxidative stress caused by alcohol, maintaining the stability of the intracellular antioxidant defense system, and alleviating liver damage; In addition, NCB can upregulate the activities of alcohol dehydrogenase and acetaldehyde dehydrogenase and accelerate alcohol metabolism, thus decreasing the blood alcohol concentration, shortening the sobriety time, and lowering the risk of liver damage caused by alcohol. Taken together, NCB has the potential to be developed as an important natural antialcoholic functional beverage.
