Objective:To study the extraction technology of Qinling Polyporus triterpenoids, and carries on the identified research for its comprehensive utilization  Methods:The content of polyporus total triterpenes was measured by UV spectrophotometry with vanillin-glacial acetic acid solution and perchloric acid as developing agent; With ethanol as solvent, using the method of solvent extraction of triterpenoid compounds. The optimum extraction is evaluated by single factor test and orthogonal test, and the structure of the triterpenoids was identified based on the physicochemical constants and spectral evidences  Results:The most optimum conditions for this extraction was adding six times amount of 95% alcohol and refluxing three times,2h once   Conclusion:The extraction process is simple, feasible, and can provide a scientific basis for the study of Qinling Polyporus.
