to saynatural plant extractWhere are they used? There are too many places that can be used. Plant extracts refer to substances extracted or processed from plants (all or a part of plants) using appropriate solvents or methods. The pharmaceutical industry, the food industry, the health industry, the beauty industry and other industries..... These industries can be used. Here are some common uses of plant extracts. You will understand what plant extracts are. What is going on for what.
1. Broccoli Extract (raw material for health care products)
A compound found in broccoli sprouts not only helps prevent cancer, but also has the potential to cure cancer. This compound is called sulforaphane and is found in a wide variety of vegetables such as kale, cauliflower, cabbage, especially It is a high concentration of broccoli sprouts. Sulforaphane can also be used as a dietary supplement for the treatment of degenerative neurological diseases (BSE). Scientists at the Texas A&M Health Science Center Research Institute and researchers in Oregon, USA, have previously Sulforaphane has been found to inhibit colon and prostate cancer cells in in vitro cell tests in the laboratory. They have now shown that the compound has similar effects in humans.
In a clinical study, 28 volunteers over the age of 50 were undergoing routine colonoscopy. The researchers also surveyed their eating habits of cruciferous vegetables. Their colon biopsies found that those who regularly ate western The orchid volunteers had higher levels of the tumor suppressor gene p16, while those who ate little or no cruciferous vegetables had very low levels of the gene.
But it seems strange that sulforaphane persists in the body for a short time, and it is not detected in the body in less than 24 hours. This may suggest that sulforaphane and its metabolites trigger some Epigenetic modifications allow downstream mechanisms and pathways to continue even if sulforaphane persists for a short period of time, at least in the short term. "Your genes, and assist your body against tumor growth.
It's not all good news, however. Sulforaphane has been shown to generally inhibit colon cancer development in animal models, but it's actually a double-edged sword. Sulforaphane can induce the expression of a protein called Nrf2, which has Antioxidant detoxification, and it is obviously beneficial to anti-cancer. However, in the late stage of cancer development, Nrf2 can also promote tumor growth and even enhance the accumulation of cancer cell plaques in arteries. Therefore, scientists believe that Nrf2 is worthwhile Further exploration is not only on cancer treatment, but also on the possible role of this protein in regulating cardiovascular disease.
2, Ginkgo biloba extract (raw material for health care products)
Ginkgo Biloba Extract (GBE), refers to the effective substances extracted from Ginkgo biloba, containing Ginkgo biloba total flavonoids, ginkgolides and other substances. It can dilate blood vessels, protect vascular endothelial tissue, regulate blood lipids, and protect low-density lipoprotein. , Inhibit PAF (platelet activating factor), inhibit thrombosis, scavenge free radicals, etc.
Efficacy of Ginkgo biloba plant extract: dilate blood vessels, protect vascular endothelial tissue, regulate blood lipids, protect low-density lipoprotein, inhibit PAF (platelet activating factor), inhibit thrombosis, scavenge free radicals, anti-hypoxia, prevent arterial spasm
3, tea plant extract (cosmetic raw material)
Tea plant extracts: Tea polyphenols are extracted from tea leaves and are the general term for polyphenols in tea leaves. Studies have shown that active substances such as tea polyphenols have detoxification and anti-radiation effects, and it is also a new type of natural antioxidant. Oxidant, has strong antioxidant effect at room temperature and low concentration, has inhibitory effect on collagenase and elastase, and can prevent the content of elastin. It has inhibitory effect on collagenase and elastase, and can prevent the content of elastin from decreasing Or degeneration, maintain skin elasticity, and achieve anti-wrinkle effect. In addition, tea polyphenols are water-soluble substances, which have the functions of disinfection, sterilization, anti-aging of skin, and reducing skin damage caused by ultraviolet radiation in sunlight.
Most of the current sunscreens are oil-soluble compounds, some of which are locally irritating to the skin. Therefore, tea polyphenols as water-soluble sunscreens with UV absorption are of great significance. Tea polyphenols can block UV rays and remove UV-induced free radicals, thereby reducing the production of melanin, inhibiting the activity of tyrosinase and catalase, so as to achieve the effect of whitening.
I believe that now everyone should have a new understanding of plant extracts. In short, it is to extract its corresponding effective ingredients from plants and apply them to other industries such as medicine, food, and beauty industries to cause greater effects.
