Objective: To optimize the extraction technology of total triterpenoids from Hypodematium sinense.
Methods: With 5% vanillin-glacial acetic acid solution and 72% sulfuric acid as chromogenic agent and the content of total tripenoids as index,using single factor experiment and orthogonal test,the optimal extraction condition was determined.
Results: The optimal conditions were solid-liquid ratio 1:12, 60% ethanol concentration, and ultrasonic extraction time of 60 min at 60 degrees C.
Conclusion: The extraction technology is feasible and can be used as extraction process of total triterpenoids from Hypodematium sinense.
