    Author: Zhang HL, Zhu J, Gao GH, Zhang MN, Li YL.
    Journal: Zhong Yao Cai; 2012 Apr; 35(4):648-50. PubMed ID: 23019915.
    Abstract:
    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.
