چکیده    this research was aimed at the qualitative and quantitative determination of three anti-nutritional factors (oxalate, phytate, and tannins) present in five wine samples produced in nigeria. the determination of tannin was done using folin-denis spectrophotometric method, the determination of oxalate was done through three processes namely; digestion, oxalate precipitation and permanganate titration. the result revealed that the five wine samples actually contained these anti-nutritional factors and these compounds were present in amounts that were not toxic to the human health. ingestion of the wine samples over a long period of time could increase the anti-nutritional content and cause serious health challenges that could affect the liver and kidney. therefore sensitization on the harms of prolonged intake of these wine samples should be a priority to the government. government should also impose a strict law that will checkmate manufacturers of these drinks so as to make sure that these drinks are properly treated.
