The Chemical Constituency of Turmeric


The chemical structure of turmeric (Curcuma longa L.) grown in eight different cities of the state of Minas Gerais in Brazil has been realized. The levels of curcuminoid pigments ranged from 1.4 to 6.14 g / 100 g and those of volatile oil from 0.97 to 7.55 ml / 100 g (dry basis). Samples from Patrocínio, Arinos and Brasilândia contained higher levels of pigments than the others.

The Patrocínio sample contained the highest volatile oil content. The average levels of ethyl ether extract, protein, fiber, ash and starch were 8.51, 7.01, 7.22, 7.81 and 39.87 g / 100 g, respectively. Laboratory extraction of the aroma-free oleoresin was performed in triplicate. Higher pigment yield in oleoresin was obtained when the volatile oil was extracted with steam and oleoresin with ethanol. The obtained oleoresin was devoid of aroma and could be used in a wider range of food applications.

Turmeric contains over 90 active components, most of which have overlapping biological activities. Here is the list of active components of Tumeric.


The important chemical components of turmeric are the compounds called curcuminoids, which include demethoxycurcumin, curcumin (diferuloylmethane) and bisdemethoxycurcumin. Of these, curcumin is the best-studied compound and averages 3.14% of the turmeric powder.

The other important curcuminoids of turmeric, bisdemethoxycurcumin, and demotheoxycurcumin work together to counter the factors responsible for coronary and autoimmune diseases that typically develop as a result of poor diet and exposure to toxins.


Turmeric (Haldi) is a rich source of essential nutrients that help improve a person’s general health and strengthen the functions of various organs. The vitamins found in turmeric are vitamin A, vitamin B, vitamin C, and vitamin E.


Turmeric (Haldi) also offers a wealth of minerals that the body needs to perform various functions. It contains calcium, phosphorus, iron, chromium, manganese, selenium, zinc, and potassium in good quantity.


Turmeric provides several carotenoids, carotenes, and xanthophylls. It is these turmeric-based ingredients that give this plant its bright orange, yellow and red colors. These carotenoids are converted to vitamin A according to the needs of the body, which helps to strengthen the immune system. They also help fight free radicals and prevent heart disease.

Starch and Protein

Turmeric also contains carbohydrates in the form of starch and protein in moderate amounts. Although turmeric is not primarily used to meet the body’s energy needs, its starch and protein content definitely adds to the nutritional value of this plant.


In addition to carbohydrates and proteins, turmeric root also contains a fat-soluble substance as well as a glucoside, turpentine, which reduces pain and inflammation. Turmeric provides essential oils such as turmerone, p-polymethyl, and zingiberene.

Cineole And Other Monoterpenes

The additional phytochemicals present in turmeric include alpha-terpineol, alpha-pinene, azulene, borneol, beta-crotene, caffeic acid, cinnamic acid, caryophyllene, eugenol, limonene, guaicol, linalool, p-cymene, turcone, turcone, p-coumaric acid and vanillic) acid, phellandrene and sabinene.

Each of these components provides unique health benefits and also works synergistically to make the whole plant more powerful and powerful than any ingredient used alone.

In addition to the phytochemical and phyto-nutritive substances, turmeric also has a high ORAC score of nearly 160,000, which means it is an extremely potent plant, which can improve a person’s health by improving body’s own resources, such as natural antioxidants, glutathione, catalase and superoxide dismutase. These substances help the body’s cells, tissues to function optimally, and protect them against oxidation.
