Identification by selective ion monitoring of 1-methyl-1,2,3,4-tetrahydro-beta-carboline in human platelets and plasma after ethanol intake.

1-Methyl-1,2,3,4-tetrahydro-beta-carboline (tetrahydroharman) has been quantified in human platelets and plasma following acute intake of ethanol using a selective ion monitoring method. It was not possible to detect this compound before ethanol intake.
