AI Technical Summary
Technical Problem
In existing technologies, the extraction rates of Ganoderma lucidum polysaccharides and triterpenoids from Ganoderma lucidum fruiting bodies are low and difficult to further improve.
Method used
A staged pulverization and multiple ethanol extraction method was adopted. By processing Ganoderma lucidum fruiting bodies with different pulverization particle sizes, ethanol concentrations, temperatures, times, and centrifugation, Ganoderma lucidum polysaccharides and triterpenes were gradually extracted.
Benefits of technology
It significantly improved the extraction rates of Ganoderma lucidum polysaccharides and triterpenes, reaching 6.68% and 7.01% respectively, which is superior to traditional methods.
