What is Chlorogenic acid:
Chlorogenic acid is a phenolic natural product isolated from the leaves and fruits of dicotyledonous plants, including the coffee bean, . Structurally, chlorogenic acid is the ester of caffeic acid with the 3-hydroxyl group of quinic acid.
a) Has a wide range of biological effects, from insect resistance to human health
b) An important factor in plant metabolism
c) An antioxidant and has anti-fungi effectivity, stronger than the antibacterial
Function:
a) Can be used as anti-infectious active ingredient
b) Has wide anti-virus, anti-bacteria effects
c) Has relatively lower toxicity and side-effects
d) Has obvious anti-infectious effects.
e) Due to its obvious anti-infectious effects, it not only can be used in pharmaceutical field but also can be used widely in many other fields like food, feed additives and cosmetics
Effectivity
a) An ester of caffeic acid and quinic acid, a major phenolic compound in coffee, the daily intake of coffee drinkers is 0.05-0.1g
b) Strong antioxidants in vitro and could therefore be contribute to the prevention of disease caused by free radicals
Chlorogenic acid, an ester of caffeic acid and quinic acid, is a major phenolic compound in coffee, but is also found widespread in plants and can be isolated from the leaves and fruit . This compound, long known as an antioxidant, also slows the release of glucose into the bloodstream after a meal.
