Polyphenols are a collective name for a group of chemical substances of plant origin, also known as polyphenols, which contain several phenolic groups in their chemical structure. The main role of polyphenols in plants is to give them different colors. For example, the yellow color of leaves of plants in autumn is due to the action of polyphenols, and the colors of dark vegetables and fruits such as green tea and grapes are due to polyphenols. Chlorogenic acid, anthocyanins, isoflavones, catechins, quercetin, curcumin, cocoa polyphenols, citrulline, rutinoside and resveratrol are among the more common polyphenolic compounds.
BOC Sciences' detection platform uses high performance liquid chromatography (HPLC) to identify samples by evaporative light scattering detector (ELSD) or DAD detector to efficiently and accurately detect changes in plant polyphenol content in samples.
