Black Rice Extract

Description

 

In order to extract high-quality rice rice as raw materials, extracted and refined, which belongs to the anthocyanins mainly composed of anthocyanins, anthocyanins (-3- cyanidin glucoside). Black rice extract was purple black to black powder.

The main specifications are: the extracts of black rice anthocyanins 5% - 25%; 25% anthocyanins contained 20% C3G (cyanidin glucoside -3-).

 

Main active ingredient

 

1.Anthocyanidin

Anthocyanin is a water-soluble pigment, can change the color of the cell with the pH of the cell, the cell liquid is acidic, red, cell liquid is alkaline blue.

Anthocyanin (Anthocyanidin), also known as flower pigment, is a kind of water-soluble natural pigment widely existing in plants. It is also the main color matter in the petals of plants, and the color of fruits, vegetables, flowers and so on. Anthocyanins are present in the vacuoles of plant cells and can be converted from chlorophyll. Under the condition of different pH value of the plant cell vacuole, the petals are colorful. The fall of soluble sugar increased, the cell is acidic, red or purple under acidic conditions, so the petals are red, purple anthocyanins, was positively correlated with anthocyanin content of the depth of its color, available spectrophotometer determination, blue in alkaline condition. The color of anthocyanin is affected by many factors, such as low temperature, hypoxia and phosphorus deficiency.

 

2.Anthocyanin

Anthocyanins (Anthocyanin) is a widely distributed in plant flavonoids (flavonoid) phytochemicals, Anthocyanins Extracted from food or plants often contain different anthocyanins, such as cyanidin, pelargonidin (cyanidin) (pelargonidin), paeonidin (petunidin), malvidin (malvidin) so, glycosides can also be divided into single, double, three glycoside glucoside glucoside structure, the different structure of the monomeric anthocyanins have different physiological activity. There are many effects of anthocyanins, such as antioxidant, anti atherosclerosis, anti insulin resistance, regulating blood lipids, including cyanidin glucoside (-3- cyanidin-3-O- beta -glucoside, Cy-3-g) is the main active component. Reports of the latest research shows that the increase of body mass of purple corn anthocyanins can inhibit the high fat diet induced obese mice, but the effective ingredients and mechanism is still not clear, that is the content of purple corn anthocyanins in 7% Cy-3-g played a major role.

 

3.Cyanidin-3-O-glucoside chloride

Cyanidin -3-O- glucoside is a kind of anthocyanin, mainly in black rice, black beans, purple sweet potato plants. The compound is usually hydrochloride, also known as cyanidin chloride -3-O- glucoside, Cyanidin-3-O-glucoside chloride. C3G analysis method is mainly high performance liquid chromatography (HPLC), soluble in methanol, ethanol, acetone, soluble in water, insoluble in chloroform, ether and other non-polar solvents. Cyanidin -3-O- glucoside (C3G) could significantly inhibit the growth of lung cancer in vitro and in vivo, the effect may be achieved by inhibiting the expression of XIAP and upregulation of Smac protein.

Modern pharmacological studies have shown that C3G has a variety of health care functions, such as anti-oxidation, anti-tumor, protection of the nervous system, and restoration of transient visual impairment. Other studies have found that C3G can be used as a plant protective agent to protect cotton leaves from the harm of cotton bollworm.
