Honeysuckle has been used as medicine for thousands of years in China. It is also widely cultivated. It is one of the most common flowers that are easy to live. Honeysuckle dried flowers are often drunk with tea, because honeysuckle has the functions of anti-inflammatory, antipyretic, liver protection, fertility resistance, hemostasis, immune regulation, blood lipid lowering, etc. The main active ingredient of honeysuckle is chlorogenic acid.

    Chlorogenic acid is widely used because it has special effects such as cholagogic, antibacterial, antiviral, increasing white blood cells, shortening coagulation and bleeding time, stimulating the physiological function of the central nervous system, and is used as an additive for health food or beverage. In addition, chlorogenic acid also has the function of increasing items and protecting color, so it is commonly used in food and fruit preservation. Chlorogenic acid used in fruit juice preservation can effectively prevent the deterioration of beverages and greatly improve the stability of strawberry and other fruit juices. Natural food antioxidants are becoming more and more popular among consumers. Chlorogenic acid is a new and efficient phenolic natural antioxidant. It can replace or partially replace the commonly used synthetic antioxidants in some foods. If a small amount of chlorogenic acid is added to lard, the oxidation stability of lard can be improved and the storage period can be extended. Adding a small amount of chlorogenic acid to the natural pigment solution can stabilize the color of the pigment. Therefore, chlorogenic acid is a good food additive. Natural polyphenols, represented by chlorogenic acid, have been found to protect collagen from free radicals such as reactive oxygen species, and effectively prevent ultraviolet radiation from damaging human skin. There are also several European patents for the use of chlorogenic acid in anti urease cosmetics, skin sunscreen and shampoo to prevent UV and hair dye damage. Japan has also developed anti-aging products by using the antioxidant properties of chlorogenic acid and its derivatives.

    To sum up,chlorogenic acidIt is an important physiological active substance. China has been extracting from honeysuckle and exporting it to developed countries in the form of raw materials, resulting in huge economic losses. As an important chemical reagent, chlorogenic acid has not yet produced medical or chemical pure manufacturers in China. Pure chlorogenic acid can only be imported in China, and the price is very expensive. Therefore, the development and utilization of chlorogenic acid resources has great social and economic benefits. In addition, China has a vast territory, and most areas are also suitable for the growth of honeysuckle. The huge output of honeysuckle provides us with sufficient raw material resources for the development of chlorogenic acid whose added value is much higher than that of honeysuckle. It can also develop into a complete industrial chain, which has a very positive significance in promoting the increase of farmers' income.
