Curcumin was first in 1870 from Curcumalonga L. in turmeric was first isolated from a low molecular weight polyphenolic compounds, the chemical structure of the 1910 double feruloyl methane, then research on its physiological and pharmacological effect has made significant progress. With the deepening research of curcumin, it has been found that it has many pharmacological activities, such as anti-inflammatory, anti oxidant, lipid regulating, antiviral, anti infection, anticancer, anticoagulation, anti fibrosis and anti atherosclerosis, and has low toxicity and little side effects. Curcumin is currently one of the world's largest selling natural edible pigments. It is a food additive approved by WHO and the US Food and drug administration. Attracting researchers is not only curcumin as a non steroidal anti-inflammatory drug, but because of its chemopreventive properties, curcumin has a wide range of Preventive Characteristics for diseases. Since modern medical research has found that many diseases of human body are related to the participation of free radicals and inflammatory reactions, curcumin's antioxidant activities and anti-inflammatory effects have attracted widespread attention from scholars both at home and abroad.

Physical and chemical editing
The main source of curcumin for Zingiberaceae turmeric (Curcuma aromatica Salisb.) Jiang Huang (C.longa L.) root, rhizome, zedoary (C.zedoaria (Berg.) Rosc.) rhizome and Araceae plants (Acorus calamus L.) calamus rhizomes.

Curcumin is orange yellow crystalline powder, slightly bitter, insoluble in water and ether, soluble in ethanol, propylene glycol, soluble in glacial acetic acid and alkali solution, red brown in alkaline, yellow in neutral and acid. The method was determined by OT-42 method. The melting range is 179~182 C.

Curcumin has strong stability and strong coloring to reducing agents. Once it is coloured, it is not easy to fade, but it is sensitive to light, heat and iron ions, and has poor light resistance, heat resistance and iron resistance.

Because curcumin molecules have two hydroxyl groups at both ends, the conjugation effect of electron cloud deviates under alkaline conditions, so when PH is more than 8, curcumin will change from yellow to red. Modern chemistry uses this performance as an indicator of acid and base.


1.food additives
Curcumin has been widely used in food industry as a commonly used natural pigment for a long time. It is mainly used for dyeing canned, intestinal products and sauce halogen products, and its quantity is determined by normal production needs. Curcumin is the main component of functional food products, which can be either ordinary foods or non food forms, such as capsules, pills or tablets. For the general food form, some yellow foods, such as pastries, desserts, drinks and so on, can be considered.
2.Chemical indicator is used as an indicator of acid and base, pH 7.8 (yellow) -9.2 (red brown).

Medical Science
Jiang Huang is a common drug, and its main bioactive components are curcumin and volatile oil. The former has the effect of reducing blood fat, anticoagulant, antioxidation, gall - gall, anticancer, and the latter mainly plays the role of anti - inflammatory, antibiosis and cough. Curcumin plays an anti-cancer role by inducing malignant tumor cell differentiation, inducing tumor cell apoptosis and inhibiting tumor growth stages. It is widely applied in clinic.

1, anticancer

Curcumin is a kind of plant polyphenol extracted from Curcuma, and it is also the most important active ingredient in Curcuma. In recent years, the research not only proves that the traditional role of turmeric, but also reveal some new pharmacological effects, such as anti-inflammatory, antioxidant, scavenging oxygen free radicals, anti human immunodeficiency virus, protecting liver and kidney, anti fibrosis and anti-cancer effect may be related to inhibition of nuclear factor kappa B and -1 transcription activator protein the activation and expression of related factors, and no obvious side effects.

2. Alzheimer's disease

Animal experiments at Duke University show that curcumin in curries can not only decompose amyloid protein in the brain of rats, but also prevent the production of this protein. Researchers point out that often eating curry may also have similar effects on people, which can help prevent Alzheimer's disease.

Many studies have shown that the accumulation of amyloid protein in the brain is one of the most important causes of Alzheimer's disease. Previous studies have shown that curcumin, the key ingredient in curry, has the effect of preventing brain nerve cell damage and improving the function of brain nerve cells.

According to the American media, researchers at the Duke University have genetically modified the mice to make many amyloid proteins in their brains. The researchers then provided foods rich in curcumin to these experimental rats. It was found that the amyloid protein in the brain of rats was decomposed, and the same recipe could prevent amyloid protein in the brains of adult rats.

3. Anti-inflammatory

Inflammation is a complex process, which is caused by cell infection and / or tissue injury, resulting in a series of chain reactions, eventually leading to the rapid development of some chronic diseases. In view of the important role of inflammation in most chronic diseases, anti - inflammatory drugs are needed to prevent it. Although some different steroidal and non steroidal anti-inflammatory drugs such as aspirin and celecoxib, furosemide test Bloven, Baotaisong can be used in the treatment of inflammatory diseases, but most of them have side effects. The study found that drug curcumin anti-inflammatory activity comparable to steroidal and non steroidal drugs, such as indomethacin, phenylbutazone, and in most cases it is safe.
