Problems solved by technology

[0006] In the 1980s, researchers at home and abroad began to study the chemical components of Ganoderma lucidum in depth, and achieved certain results. So far, more than 200 compounds have been successfully isolated and their molecular structures identified; but these works are all carried out in laboratories. Yes, the amount of compound obtained is very small, which greatly affects the development and utilization of Ganoderma lucidum triterpenes. Therefore, it is of great theoretical and practical significance to study the industrialization technology of the extraction and purification of triterpenoids
[0008] The traditional alcohol extraction method usually needs to consume a large amount of extraction solvents, and the use of a large amount of organic solvents will have adverse effects on the human body and the environment
[0009] Patent No. CN1560072A discloses a method for preparing Ganoderma triterpenes and Ganoderma polysaccharides from Ganoderma lucidum. After the dried Ganoderma lucidum is crushed, supercritical CO 2 Extraction technology extracts Ganoderma lucidum triterpenoids, and then uses low-temperature extraction and rapid concentration technology to obtain Ganoderma lucidum polysaccharides, but adopts supercritical CO 2 The equipment required for the extraction technology is relatively large, the operation is difficult, and the production cost is high
[0010] Compared with other fungi, Ganoderma lucidum fruiting body has a high degree of lignification and a complex and compact structure, while triterpenes and Ganoderma lucidum polysaccharides are distributed inside the cells. The extraction rate is low through traditional extraction methods, and most of the active ingredients are retained in the residue. , resulting in a waste of resources
[0011] Patent No. CN105294875B discloses a method for extracting Ganoderma lucidum polysaccharides from Ganoderma lucidum fruiting bodies. After the Ganoderma lucidum fruiting bodies are pulverized, the cellulose and lignin that make up the cell wall are reacted with the oxidation system of sodium chlorite-glacial acetic acid. Digestion and fracture release more active substances, which greatly improves the extraction efficiency of polysaccharides. However, Ganoderma lucidum triterpenoids and polysaccharides are mostly used in medicine and health care, and sodium chlorite is highly carcinogenic. Extracting products with this method is likely to cause safety hazards
