title: Ratio of the R and S enantiomers of salsolinol in food and human urine.
abstract: Salsolinol is present in human fluids and tissues as well as in some foods and beverages. It was found previously that the R enantiomer of salsolinol predominates in human urine whereas the S enantiomer predominates in Port wine. In this study a new methodology for measuring the proportion of the R and S salsolinol enantiomers in dried banana and human urine is described. In dried banana, a food particularly rich in salsolinol, the R/S ratio was found to be very near to 1. In urine from additional healthy volunteers, the presence of only the R enantiomer was detected. The origin of urinary salsolinol and its enantiomeric composition are discussed with respect to exogenous salsolinol.
