Abstract
A method efficiently produces hydroxycinnamic acids having a high quality, from a cellulose-containing biomass. More specifically, the method includes the steps of: obtaining an alkaline filtrate by allowing an alkaline aqueous medium to pass through a cellulose-containing biomass; obtaining a hydroxycinnamic acid extraction liquid by allowing the alkaline filtrate to repeatedly pass through the cellulose-containing biomass; and separating the hydroxycinnamic acid from the hydroxycinnamic acid extraction liquid.
