The Application of Supercritical Co2 Extraction in Pharmaceutical & Health-care Products Industry
Using supercritical Co2 to extract and separate effective components (such as various alkaloids, aromatic and oily components) in many medicinal plants is a key field of research and application of supercritical Co2 extraction. In antibiotics, organic solvents such as acetone and methanol are often used in traditional methods, and there is also the problem of residual solvent pollution. If supercritical Co2 is used, this problem can be completely solved. At present, there have been cases where supercritical Co2 is used to extract the effective ingredients for treating cancer in plants and has been applied clinically.
Fish oil and omega-3 fatty acids are beneficial to health and become important health care products for human beings to pursue health. These lipids can also be obtained from phytoplankton. Lipids obtained by supercritical Co2 extraction do not contain cholesterol. Supercritical extraction of lipids from algae Studies have shown that chlorophyll will not be extracted by supercritical Co2, thus eliminating the bleaching process of traditional solvent extraction.
In addition, using supercritical Co2 to extract ginkgo flavonoids from ginkgo leaves, polyethylenically unsaturated fatty acids (DHA, EPA) from fish viscera and bones, sea buckthorn oil from sea buckthorn seeds, lecithin from egg yolk, and Extracting active ingredients with unique curative effects against cardiovascular and cerebrovascular diseases from plants Cnidium chinensis, Morus alba bark, licorice root, Comfrey, safflower, and evening primrose has been quite mature.
