Guideline for High‐Performance Liquid Chromatography Detection of Anthocyanins
AgriFood: Journal of Agricultural Products for Food, EarlyView.ABSTRACT Anthocyanins, as water‐soluble natural pigments widely present in plants, have various biological activities such as antioxidation and anti‐inflammatory, and are widely used in the fields of food, cosmetics, and medicine. However, because of the presence of unstable phenolic hydroxyl groups in their structure, they are prone to degradation due
