What are the effects of plant extracts?

Plant extracts are plants as raw materials, and the need for the use of the final product extracted.Through the physical and chemical extraction and separation process, directional acquisition and concentration of one or more active ingredients in plants without changing their effective ingredient structure and the product formed. According to the different components of the extracted plant, it forms glycosides, acids, polyphenols, polysaccharides, terpenes, flavonoids, alkaloids, etc .; according to different traits, it can be divided into vegetable oils, extracts, powders, lenses, etc. Heart extracts, tomato extracts, cherry extracts, aloe extracts, ginkgo leaf extracts and other plant extracts have been widely used in plant medicines, food additives, functional foods, daily chemicals, plant-derived pesticides and veterinary medicines, etc. Production area. The plant extract industry has developed in the last 10 years and is a fringe industry between the pharmaceutical, fine chemical and agricultural industries.

The extract industry in China is an emerging industry. In the late 1980s, along with the increasing demand for botanical medicines and natural health products in the international market, China's professional extract companies began to appear. The "export fever" represented by the export of Licorice, ephedra, ginkgo biloba, and Hypericum perforatum extracts Successively formed. After 2000, many Chinese patent medicine companies, fine chemical companies, and chemical raw material manufacturing companies also began to get involved in the extract market. The participation of these companies has greatly promoted the development of the extract industry in China, but it has also led to the extract industry in China. A period of "price scuffles" emerged over a period of time. After decades of development, most of the extract companies in China have greatly improved the production process and quality inspection level. The products have basically met the requirements of the international market, and the benefits of industrial scale have gradually emerged. In 2016, the scale of China's plant extract market reached 20.512 billion yuan, an increase of 9.73% year-on-year. In 2017, it will reach 22.6 billion yuan, an increase of 10.18% year-on-year.

Most of the Plant Extracts in China are taken from Chinese herbal medicines and plant resources that are unique to China. Hunan, Shaanxi and Sichuan, which have resource advantages, are the three main producing areas. In general, the development of plant extracts in China is not long, the entry barrier is relatively low, there are many enterprises in the industry, and the competition is fierce.

The development of Chinese herbal extracts is an efficient way to increase the added value of Chinese herbal medicines and pieces. It is expected that the market size of Chinese plant extracts will reach about RMB 34.1 billion in 2022, an increase of about 50% from 2017.

Plant extract product efficacy
Stop cancer

American scientists say that through their research on bladder cancer, they have confirmed that green tea extract can effectively suppress the development of cancer tumors, while not damaging healthy cells. The research team led by Chinese-American scientists believes that green tea extract may become an effective anti-cancer drug.
This result was published in the Journal of Clinical Cancer Research that day. Jianyu Rao, an associate professor at the University of California, Los Angeles, who hosted the study, said that their results "enhanced the understanding of the mechanism of action of green tea extract." If people understand the mechanism of green tea extract to suppress tumors, it is possible to determine which type of cancer patients can benefit from green tea extract.

The researchers wrote in the paper that the development of cancer tumors is closely related to the spreading movement of cancer cells. For cancer cells to move, they must start a cellular process called "actin remodeling". Once this process is activated, cancer cells can invade healthy tissue, causing the tumor to spread. The green tea extract can disrupt the "actin remodeling" process, causing cancer cells to stick together and hinder their movement. In addition, it can accelerate the aging of cancer cells.

Cancer cells are "aggressive", and green tea extract breaks its "aggressive" path, restricting cancer cells and making them "localized", making cancer treatment and prognosis relatively simple.

Unlike previous studies, the green tea extracts they use are very similar to the green tea they drink, which means that regular drinking green tea may have some anti-cancer effect, at least to enhance the body's defense against cancer. However, the researchers also believe that they have only tested a limited number of bladder cancer cell lines, and further research is needed to reveal the anti-cancer mechanism of green tea.

Other scientists commented on the day that the results of this study further confirmed the potential of green tea in preventing and treating cancer. Especially in the treatment of bladder cancer, new achievements can help to find susceptible people with bladder cancer and reduce the incidence.

Antioxidant
Since Gomberg proposed the theory of free radicals (tripheylemthylradical) in 1900, people's research on free radicals has gradually deepened. Although the traditional synthetic antioxidants have relatively strong antioxidant capacity, they are potentially toxic for long-term consumption, and some may even cause teratogenic and carcinogenic effects, so they are increasingly rejected by people; and bee pollen is collected by bees from flowers Pollen grains, containing flavonoids, vitamins, hormones, nucleic acids, enzymes and trace elements, have anti-aging effects and are good antioxidant foods. The antioxidant effects of Pueraria lobata, Eucommia ulmoides leaves, Chinese wolfberry, Hovenia dulcis Thunb, Poria cocos, Schisandra chinensis, Ginkgo biloba, bamboo leaves, lemon, citrus and propolis have all been proved by experiments. Therefore, screening substances with anti-oxidation and free radical scavenging activities from Natural Products is of great significance to the food and pharmaceutical industries.
