Biosynthesis of synephrine in citrus

Phytochemistry, 1969
Abstract Synephrine is formed in citrus by a pathway involving tyramine and N-methyltyramine. Octopamine is probably not an important intermediate. 14 C-labeled tyramine was converted to N-methyltyramine, hordenine, octopamine, and synephrine in one of the citrus cultivars studied.
