Herbal Extract

Plant extracts refers to substances extracted or processed from plants (all or part of plants) with appropriate solvents or methods. They can be used in pharmaceutical industry, food industry, daily chemical industry and other industries.

There is a conceptual intersection between plant extracts and Chinese herbal extracts. The raw materials of plant extracts in China mainly come from Chinese herbal medicine. Therefore, domestic plant extracts can also be called traditional Chinese medicine extracts to some extent. They are generally included in the category of traditional Chinese medicine products in China's export trade statistics.

Development History

China's plant extracts come from the traditional Chinese medicine industry, and the overall development time is relatively late. In the 1970s, some Chinese herbal medicine factories began to use mechanical equipment to extract active ingredients, but only as part of production, plant extracts have not been produced on a large scale. Until the 1990s, the international trend of returning to nature rose, and people began to tend to use natural plant products. During this period, China's foreign trade rose, and China's Plant Extract industry was getting better and better. In the 21st century, with the application of more advanced extraction methods such as enzymatic extraction, ultrasound, supercritical extraction, membrane separation technology and microwave extraction technology, the yield of extract has been greatly improved, and China's plant extract industry has entered a golden period of development. From 2010 to 2015, the production capacity and export volume of plant extracts increased steadily and rapidly every year, and the proportion of plant extracts in the export of traditional Chinese medicine also increased a lot. Since 2016, the market situation of plant extracts has changed.
