Background

The plant extract industry has been developed in the last 20 years and is an emerging industry combining the industries of medicine, fine chemicals and agriculture. The plant extract refers to a substance extracted or processed from a plant (whole or a part of the plant) by using a proper solvent or method, and can be used in the pharmaceutical industry, the food industry, the health industry, the beauty industry and other industries. The plant extract is a product formed by taking plants as raw materials, directionally obtaining and concentrating one or more active ingredients in the plants through a physical and chemical extraction and separation process according to the requirements of the application of an extracted final product, and not changing the structures of the active ingredients. According to different components of the extracted plants, glycoside, acid, polyphenol, polysaccharide, terpenoid, flavone, alkaloid and the like are formed; according to different properties, the plant oil can be divided into vegetable oil, extract, powder, crystalline lens and the like.

The data shows that in the first half 2014, 1074 enterprises in China export plant extract commodities to the outside, and the quantity of the exported plant extract commodities is slightly increased compared with that of the exported enterprises in the same period in the last year. The export account of the civil enterprises is up to 50.4%, the civil enterprises are far ahead, and the contribution is the largest. The percentage of "three-funded" businesses immediately following this is up to 35.4%. The plant extract industry in China is developed for less than 20 years, and people's camp plant extract enterprises grow and develop under the condition of lack of ' care ', so that the challenge of coping with financial ' tsunami ' is continuously strengthened.

Under the influence of new medical models, plant extract products with functionality or activity are gaining favor. At present, the plant extract industry develops more and more rapidly, exceeds the growth rate of the drug market and becomes an independent new industry. With the rise of the plant extract market worldwide, the Chinese plant extract industry must become a new strategic pillar industry for the development of national economy and society.

The plant extract is the main force of export of Chinese medicine commodities, and the export accounts for more than 40 percent of the total export of Chinese medicine products. Although the plant extract industry is an emerging industry, it has developed rapidly over the last two decades. Statistical data show that the export of Chinese plant extracts reaches 11.3 hundred million dollars in 2011, the year-by-year increase is 47%, and the composite increase rate in 2002-2011 reaches 21.91%.
