Notes:
Constit. of sweet clover (Melilotus officinalis) and yeast An oxidative deaminated metabolite of p-tyramine. Also a metabolite of tyrosine via enteric bacteria. The bacterial origin of this compound was confirmed by the finding that this compound in urine decreased significantly after the use of the antibiotic neomycin.
