英文摘要
It was reported that 4'-O-methylpyridoxine (MPN) is responsible for Gin-nan food poisoning by our group. In this study, we newly suggested that MPN-5'-glucoside, rather than MPN, is consumed when we eat Ginkgo biloba seeds. Additionally, MPN-5'-glucoside had a lethal effect in mice, as well as MPN. A portion of orally administered MPN-5'-glucoside was directly absorbed and a portion of the other was hydrolyzed to MPN in intestine. This is the first study which suggested contribution of absorption and hydrolysis of MPN-5'-glucoside in intestine to the first step of occurrence of Gin-nan food poisoning.
