Caffeic acid reduces lipid accumulation and reactive oxygen species production in adipocytes

Caffeic acid (CA) is a hydroxycinnamic acid, a group of natural organic phenolic compounds used in folk medicine and in foods for the prevention and treatment of obesity. CA is present in a variety of plants, as it is an intermediate in secondary metabolism. It is found in coffee, wine and olive oil. The aim of this work was to study the influence of caffeic acid (CA) on the reduction of intracellular lipid...
