Research progress on analysis methods of procyanidins

Abstract

Procyanidins (PC for short) is a very complex secondary metabolite of plant polyphenols, rich in grape skins, seeds, apples, hawthorn, tea and other plants. Studies have shown that the intake of procyanidins can regulate cell apoptosis through its anti-oxidation effect, and play a role in maintaining body health, delaying aging and preventing diseases. However, there is no unified standard for detection and quantitative analysis methods so far, making the separation, purification, and characterization of such products always be a technical problem that plagues market quality evaluation. Therefore, this article summarizes and summarizes PC analysis methods, including spectrophotometry, high performance liquid chromatography and other analysis methods.
