Umbellic acid (24-dihydroxycinnamic acid) is a hydroxycinnamic acid. It is an isomer of caffeic acid.It is a precursor in the umbelliferone biosynthesis pathway. Umbelliferone is a phenylpropanoid and as such is synthesized from L-phenylalanine which in turn is produced via the shikimate pathway. Phenylalanine is lysated into cinnamic acid followed by hydroxylation by cinnamate 4-hydroxylase to yield 4-coumaric acid.
