Traditional Chinese medicine extraction technology was a major breakthrough
Traditional Chinese medicine extraction technology has made a major breakthrough after years of efforts , the world's cutting-edge supercritical fluid extraction Yiyiren lipophilic anti-tumor active ingredients extracted project successfully tested, the modernization of Chinese medicine took a big step forward and demonstrate the huge industry prospect of a year can save hundreds of thousands of tons of oil resources.
Supercritical fluid extraction is a worldwide emerging in nearly 30 years the research focus , as it is close to the density of the liquid , with higher extraction capacities to achieve the purpose of extraction and isolation of active ingredients . Especially in the "energy crisis" urgent and " environmental pollution" increasingly severe cases , this technology in the chemical, energy, fuel , medicine, food and other fields has attracted sustained attention. Country
1980s began supercritical fluid technology development and research, food and other fields also conducted a primary application , but did not achieve substantial breakthroughs . In recent years, China's implementation of the process of modernization of Chinese medicine , supercritical extraction technology is classified as modern medicine and efficient extraction and separation of the key new technologies , the development and industrialization of the formation of the " hot hot ." Particularly in the non-polar carbon dioxide as extractant , as non-flammable, non-toxic, chemically inert , inexpensive , safe , no solvent residues , no pollution, easy to recycle , etc., and the critical temperature close to room temperature , the pressure in the middle pressure . Antioxidant sterilization of fatty material components with high extraction capacity , ideal for fat-soluble active ingredients of traditional Chinese medicine extraction .
    Zhejiang Medicine Task Force . Ten years ago began to supercritical carbon dioxide extraction applied to the Chinese medicine industry laboratory research. The study in 1997 was listed as Zhejiang university major scientific and technological projects , the feasibility of obtaining experimental data base , was listed as Zhejiang Science and Technology " 1999 the first major high-tech industrialization projects ", in 2000 became the Ministry of Science and " small and Medium enterprises technology Innovation and Technology Fund ." Two years ago , the research group to finalize the extraction kettle , kettle analytical separation column and the pressure , temperature, carbon dioxide flow and extraction time of process parameters, creatively using a combination of extraction and fractionation processes , to achieve the extraction step . Product yield increased to 13.3% . Cost reduction of 22% , and save tons of oil resources could reach an annual production capacity of 36.5 tons .
    This success marks the supercritical extraction in the field of Chinese medicine on the industrial application , in 2003 the State Food and Drug Administration approved formally put into production, since products 100% pass rate . In ensuring stability on the basis of technology , supercritical extraction technology May this year by the State Intellectual Property Office of technology patents , in the first half of the experts , the experts unanimously found that the technology " in the domestic and international industrial applications in medicine leader "," in the process of modernization and internationalization of Chinese medicine has a role model . " Not long ago, this achievement also won the China Association of Chinese Medicine Science and Technology Award .
