Echinacea purpurea extract is a kind of herb flowering plant. It contains chrysanthemic acid, polysaccharide, alkane amine and other active components. It is thought to be an immune hypnotic (stimulant) that strengthens the lymphatic system. Active, antibacterial and antiviral effects can be used to prevent or treat colds and promote wound healing in the early stages of disease.

Echinacea,is a famous perennial herb in Europe and North America which is used to treat insect and snake bites in India. It originated in North America and it is an Indian insect snake bite drug. The purple cone flower is used to treat snake venom, mosquitoes and sores. It has been used for more than 100 years. Later, scientists found that Echinacea extract has the function of improving the human body's natural defense system, especially in the face of increased resistance to infectious agents and the effect is excellent. Later, Echinacea appeared in the prescription notes of doctors all over the world in history. In addition, Echinacea purpurea extract is rich in nutrients.

Echinacea purpurea extract contains a variety of active ingredients, mainly including phenolic acid, polysaccharide, alkylamine, polyethylene, glycoprotein and so on. Among them, phenolic acid, polysaccharide and alcohol amide are closely related to the regulation of immune system. The content of phenolic acid in Echinacea purpurea is quite high, which has a variety of biological activities, including anti-inflammatory, prevention of thrombosis, inhibition of tumor proliferation, oxidation, scavenging free radicals and so on.

Echinacea extract contains many ingredients, but it has almost no specific pungent taste, usually just fresh grass flavor, no bitter or sour taste. Therefore, there are many purple coniferous pollens on the market, which are used to make a variety of health food, and its natural extract is also widely used in the field of health products. At present, hundreds of products on the global market contain purple cones.

The phenols in the extracts protect the enzymes and receptor cells in plants and protect plants from infection and ultraviolet radiation. Phenols also have antioxidant properties and are good for human health. At the same time, Echinacea extract also contains alkyl amides or amino alcohols, polysaccharides, glycoproteins and caffeine derivatives, which affect and improve the immune system. Therefore, a series of studies hope to achieve low-cost and efficient industrial chemical mass production by extracting monomer compounds from Echineacea Purpurea and using monomer to extract pure compounds, so as to ensure its effectiveness. However, it was found that the antibacterial effect of the isolated compounds was not as good as that of the natural mixed extracts. The main reason is that there is a good synergy between the complex biochemical components in Echinacea purpurea. The effect is that when these components exist alone, they are much more effective than when compounds and a natural combination of multiple components exist simultaneously.
