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.
