THE PHENOLIC ACIDS IN WHEAT: II. NATURAL OCCURRENCE OF ORTHOFERULIC ACID (2-HYDROXY-3-METHOXYCINNAMIC ACID)

Abstract
Orthoferulic acid was isolated in small amount (5 mg/300 g fresh wt.) from an alkaline hydrolyzate of an ethanolic extract of wheat shoots. This phenolic acid was found in shoots only at certain stages of growth and was absent from embryos, grains, or roots. Traces of 8-methoxycoumarin were also shown to be present.
