Application
4-Hydroxyphenylacetic acid may be used as an analytical reference standard for the quantification of the analyte in beer samples using high-performance liquid chromatography (HPLC) coupled to an electrochemical coulometric detector (ECD). It may also be used as an analytical standard for the quantification of the analyte in goat rumen fluid using HPLC with UV detection.
General description
4-Hydroxyphenylacetic acid, a hydroxyphenylacetic acid metabolite, is reported to be produced via the bioactivation of kaempferol by intestinal microflora. It belongs to the class of dietary plant phenolic compounds, with a broad-spectrum of biological properties such as modulation of enzymatic activity, metal chelation, free radical scavenging, prevention of several human diseases, mainly atherosclerosis and cancer.
