Production of coumaric acid from sugarcane bagasse

Innovative Food Science and Emerging Technologies, 2009
Abstract Phenolic acids were released from sugarcane bagasse by alkaline hydrolysis at 30 °C for 4 h; The alkaline hydrolysates were ultrafiltrated, the permeates purified with anion exchange resin. The phenolic acids bound by the resin were desorbed by a mixture of water–ethanol–HCl solution (36: 60: 4) after washing the resin with water, ethanol ...

Synergistic inhibitory effects ofp-coumaric and ferulic acids on germination and growth of grain sorghum

open access: yesJournal of Chemical Ecology, 1977
The data support the hypothesis that there is a synergistic phytotoxic effect when p-coumaric and ferulic acids are found together. Equimolar mixtures of both acids showed greater reduction in sorghum seed germination, shoot elongation, and total ...

Spectrophotometric Characterization of the Action of Tyrosinase on p-Coumaric and Caffeic Acids: Characteristics of o-Caffeoquinone

open access: yesJournal of Agricultural and Food Chemistry, 2017
New methods are proposed to determine the activity of tyrosinase on caffeic and p-coumaric acids. Because o-quinone from caffeic acid is unstable in its presence, it has been characterized through spectrophotometric measurements of the disappearance of ...

Structural, thermal and quantum chemical studies of p-coumaric and caffeic acids

open access: yesJournal of Molecular Structure, 2015
Two hydroxycinnamic acids viz., p-coumaric, and caffeic acids have been extracted and purified from Parthenium hysterophorus, subsequently characterized by elemental analysis, FT-IR, NMR, single crystal X-ray crystallography.
